Security force assistance

Security force assistance (SFA) is the organized effort by a state or coalition to train, advise, equip, and otherwise support the security forces of a partner nation, aiming to build their capabilities for internal security, counterinsurgency, or broader strategic goals. Primarily associated with U.S. military doctrine since the post-9/11 era, SFA emphasizes enabling partners to operate independently rather than direct combat involvement by the assisting force, as formalized in Department of Defense directives and Joint Publication 3-22. Historically rooted in Cold War-era advisory missions, such as U.S. support to in the and Soviet assistance to allies like , SFA has evolved into a core component of great-power competition, with the U.S. establishing specialized units like Security Force Assistance Brigades (SFABs) in 2017 to professionalize these efforts. Notable examples include U.S. training of Philippine forces against since 2002 and multi-billion-dollar programs in and to develop national armies capable of sustaining operations post-withdrawal. Despite doctrinal refinements and investments exceeding tens of billions of dollars, empirical assessments reveal SFA's mixed record, with frequent failures in fragile states due to host-nation political , , insufficient local , and external undermining built capacities. High-profile collapses, such as the rapid disintegration of forces in 2021 after two decades of assistance, highlight causal factors like on foreign and lack of will to fight, prompting critiques that SFA often prioritizes short-term tactical gains over sustainable institutional reforms. Proponents argue it remains essential for strategic denial and partner , but underscores the need for rigorous vetting of recipient and with broader political strategies to avoid enabling repression or prolonged .

Definitions and Core Concepts

Primary Definition

Security force assistance (SFA) is defined as the unified action by U.S. military forces to generate, employ, and sustain local, host nation, or regional in support of a legitimate , typically involving advising, , equipping, and institutional capacity-building to enable partners to address internal and external threats independently. This , formalized in U.S. publications such as Joint Doctrine Note 1-13, emphasizes partner-led security operations where U.S. personnel provide enablement rather than assuming primary roles, aiming to foster in host nation forces. SFA activities are executed across phases, from assessment and planning to sustainment, often integrating , sharing, and alignment to build enduring capabilities. Core to SFA is its focus on institutional development, including reforming partner military , command structures, and sustainment systems to align with operational needs, as evidenced by U.S. programs that have trained over 1,400 Iraqi soldiers in six-week cycles during post-2014 stabilization efforts. Unlike direct , SFA prioritizes measurable outcomes such as improved host nation force readiness metrics—e.g., rates from advisory-led and independent operation thresholds—to mitigate dependency and enhance strategic stability. Specialized units like the six Security Force Assistance Brigades (SFABs) fielded by the U.S. since 2018 embody this approach, deploying teams of 50-800 personnel tailored for advisory missions in permissive environments. SFA's objectives extend beyond tactical proficiency to strategic goals, such as countering malign from adversaries like or by strengthening allied defenses, as outlined in National Defense Strategy guidance linking SFA to great power competition. Empirical assessments, including post-mission evaluations from operations in and , highlight challenges like cultural mismatches and in partner forces, underscoring the need for vetted personnel and phased transitions to avoid over-reliance on U.S. support. Despite these hurdles, SFA remains a vital tool for indirect U.S. , with stressing adaptability to host nation contexts over templated solutions. Security force assistance (SFA) differs from (FID) primarily in scope and focus; FID emphasizes U.S. support to a nation's efforts against internal threats such as insurgencies or lawless groups, integrating activities to foster and , whereas SFA prioritizes building partner ' capabilities across a broader spectrum of threats, including conventional external , without mandating the internal threat emphasis central to FID. For instance, U.S. Army in ATP 3-96.1 outlines SFA as applicable to organizing, training, equipping, and advising foreign in peacetime or environments, extending beyond FID's host-nation-led internal model to include institutional reforms for sustained . In contrast to standalone military advising, which centers on providing expert guidance to foreign commanders on tactics, operations, or without broader logistical or , SFA integrates advising as one element within a comprehensive framework that also encompasses equipping forces with , conducting joint training exercises, and reforming doctrines and structures to enhance long-term operational effectiveness. This holistic approach, as detailed in the Commander's for Security Force Assistance, distinguishes SFA by requiring advisors to address systemic deficiencies, such as chains or personnel systems, rather than limiting roles to observational counsel, as seen in earlier advisory groups like Military Assistance Advisory Groups that focused primarily on doctrinal transfer. SFA is a of building partner capacity (BPC) efforts but narrower in application; BPC encompasses interagency activities to improve a partner's overall or functions, including non-security sectors like or , while SFA specifically targets security force development through Department of Defense-led programs, excluding direct U.S. combat engagements and emphasizing partner-nation ownership to avoid dependency. Unlike (COIN) operations, where U.S. forces often conduct partnered kinetic missions alongside host forces—as in post-2003—SFA doctrine mandates minimal U.S. , focusing instead on enabling the partner to assume lead roles, with metrics tied to the partner's independent execution rather than joint outcomes. This separation ensures SFA avoids escalating U.S. involvement into , a risk highlighted in evaluations of advisory teams where blurred lines undermined partner autonomy. Security cooperation programs, such as those under Title 10 authorities for arms transfers or exchanges, differ from SFA by prioritizing diplomatic and exchanges without embedded operational advising; for example, security assistance funding mobile training teams contrasts with SFA's sustained brigade-level embeds, like those of Security Force Assistance Brigades (SFABs) activated since 2017, which conduct persistent assessments and reforms tailored to theater plans. Overall, these distinctions underscore SFA's emphasis on scalable, low-footprint capacity enhancement to align with strategic deterrence, avoiding the associated with more intrusive practices.

Theoretical Foundations

Security force assistance (SFA) draws from political realism in , viewing it as a mechanism for states to bolster allies' military capacities to deter aggression, maintain regional balances of power, and secure national interests without direct . This approach recognizes that SFA shapes recipient states' power dynamics and elite incentives, prioritizing political outcomes over isolated tactical gains. For instance, U.S. efforts in the since 2002 exemplify how SFA curbs transnational threats like affiliates by building partner self-sufficiency, aligning with realist imperatives to avoid overextension. A Clausewitzian framework further grounds SFA, conceptualizing it as an instrument of policy where military assistance must integrate with political , rather than devolving into apolitical training metrics. Carl von Clausewitz's emphasis on war as a continuation of underscores that SFA failures, such as in where over $80 billion yielded fragile forces collapsing in 2021, stem from prioritizing quantifiable outputs like trainees over strategic coherence and recipient political will. Successful cases, like Ukraine's adaptation of Western aid since 2014, demonstrate "reverse SFA" where recipients drive reforms amid existential threats, highlighting the need for advisors to navigate local political terrains rather than impose external models. Contemporary analyses incorporate principal-agent theory and to address SFA in fragile or fragmented contexts. Principal-agent dynamics reveal risks of misaligned interests, where recipients exploit assistance for regime preservation amid divided loyalties, distinct from security sector reform's governance focus or peacekeeping's neutral monitoring. In complex adaptive systems, advisor-partner interactions produce emergent, non-linear outcomes influenced by feedback loops and cultural intersubjectivity, as seen in Colombia's effective absorption versus and Afghanistan's mismatches from U.S.-centric templates. These frameworks stress assessing institutional and to foster sustainable partner forces.

Historical Development

Pre-Modern and Colonial Precedents

In ancient empires, practices akin to security force assistance emerged through the integration and training of allied or provincial forces. The systematically recruited from non-citizen provincials across its territories, subjecting them to rigorous training in drill, tactics, and equipment standards to operate alongside legions. These units, organized into cohorts of approximately 500 infantrymen or alae of 500 cavalrymen, provided essential specialized roles such as and , eventually comprising roughly half of the army's manpower by the AD. This approach enhanced imperial control by building capable local contingents loyal through service, with earning after 25 years, fostering long-term alignment with interests. During the colonial era, European powers expanded this model by raising and advising native armies in and to extend control with minimal metropolitan troops. The formalized the system in the mid-18th century, beginning with the in 1748 and expanding after the 1757 , where 2,100 sepoys supported Robert Clive's victory over a larger force. By 1857, the included over 232,000 sepoys trained in European-style , , and under officers, enabling conquests across the subcontinent and deployments to imperial wars in and . This reliance on advised local forces reduced costs but exposed vulnerabilities, as evidenced by the 1857 Indian Rebellion, where cultural insensitivities like greased cartridges triggered widespread mutiny among 139,000 sepoys, killing thousands of personnel before suppression. Parallel efforts occurred in , where organized the Tirailleurs Sénégalais in 1857 from West African recruits, training them in French military doctrine for colonial pacification and expeditions, numbering about 15,000 by . Similarly, the Belgian in the , established in 1885, employed European officers to drill local askaris in marksmanship and patrols, enforcing Leopold II's rubber quotas through brutal enforcement that claimed millions of lives amid documented atrocities. These colonial precedents demonstrated how advising indigenous forces amplified European reach but often sowed seeds of instability due to mismatched loyalties and exploitative oversight, contrasting with modern SFA's emphasis on partner sovereignty.

Cold War Era Applications

During the , security force assistance emerged as a key mechanism for the and to extend influence through proxy conflicts, training and advising allied militaries to counter ideological rivals without risking direct confrontation. The U.S. established Military Assistance Advisory Groups (MAAGs) in multiple nations to professionalize host forces against communist insurgencies and expansions, such as in , the , , and , where advisors focused on logistics, training, and doctrinal reforms. These efforts were driven by containment doctrine, with MAAG personnel embedding at unit levels to enhance operational capabilities, though outcomes varied due to host nation political fragilities and advisor limitations in addressing internal governance issues. The represented the pinnacle of U.S. advisory operations, with MAAG Vietnam formed on November 1, 1950, initially capped at 342 advisors under Geneva Accords limits, expanding to 685 by 1955 amid rising threats. President Kennedy authorized surges, reaching approximately 16,000 military advisors by late 1963, who trained the Army of the Republic of (ARVN) in tactics, equipment use, and staff functions through the (MACV) after 1962. Despite providing over $1 billion in annual aid by the early 1960s, effectiveness was hampered by ARVN corruption, desertions exceeding 100,000 annually in some years, and mismatched U.S. conventional focus against , contributing to reliance on direct U.S. combat intervention by 1965. The mirrored these efforts, dispatching military advisors to support Marxist regimes in and , emphasizing ideological alignment and rapid force modernization. In , following the 1975 MPLA victory, the USSR provided over $4 billion in by the mid-1980s alongside 1,500 to 1,700 advisors who trained the People's Armed Forces for the Liberation of Angola (FAPLA) in and operations against rebels and South African incursions. Advisors, numbering around 1,000 by the late 1970s, embedded in command structures but struggled with cultural adaptation and overreliance on surrogates, leading to tactical setbacks like failed offensives in 1987-1988 due to poor intelligence integration. In Afghanistan, Soviet advisory presence predated the 1979 invasion, with hundreds assisting Afghan forces from the under aid agreements, escalating to 4,500 advisors by April 1979 to bolster the amid rebellions. These specialists reorganized units, supplied fighters and tanks, and conducted joint training, yet failed to stem mujahedin gains due to ethnic fractures and advisor vulnerabilities to ambushes, foreshadowing the full intervention's 15,000 Soviet casualties over a decade. Overall, SFA highlighted causal challenges: while materially bolstering partners short-term, success hinged on host political will and local buy-in, often absent in ideologically imposed alliances, resulting in unsustainable dependencies evident in both superpowers' post-withdrawal partner collapses.

Post-Cold War and 9/11 Transformations

Following the in 1991, U.S. security force assistance evolved from Cold War-era proxy support to addressing post-bipolar instability, including humanitarian interventions and . Operations in under Operation Restore Hope (December 1992–March 1994) involved limited training of local militias amid famine relief efforts, while NATO-led missions in the from 1995 onward, such as in Bosnia, incorporated advising nascent local security units to foster stability amid ethnic conflicts. These engagements underscored a doctrinal shift toward "operations other than war," with assistance remaining episodic and largely confined to special operations forces rather than a core conventional mission. The September 11, 2001, terrorist attacks prompted a profound transformation, integrating SFA into (COIN) frameworks within the Global War on Terror. In Afghanistan's , U.S. provided critical advising to fighters, enabling the Taliban's rapid ouster by December 2001 and highlighting SFA's potential in . This success spurred formalized structures, including the Combined Security Transition Command–Afghanistan (CSTC-A) by 2006, which coordinated training, equipping, and ministerial capacity-building for the Afghan National Security Forces amid escalating . In Iraq following the 2003 invasion, SFA scaled dramatically to rebuild security institutions post-regime collapse. The Multi-National Security Transition Command–Iraq (MNSTC-I), activated on June 28, 2004, led efforts to train, equip, and organize Iraqi and units, establishing centralized academies and distributing equipment to counter . By emphasizing transition to host-nation lead, these initiatives reflected a broader doctrinal pivot formalized in U.S. Field Manual 3-24 (December 2006), which positioned SFA as essential to by prioritizing sustainable partner capabilities over direct combat. Yet, assessments revealed systemic issues, including corruption and dependency, limiting long-term effectiveness despite billions invested.

Institutionalization in the 2010s

The 2010 Quadrennial Defense Review directed the U.S. military to strengthen and institutionalize general purpose force capabilities for security force assistance, marking a shift toward embedding SFA as a across conventional units rather than relying primarily on forces. This emphasis responded to lessons from and , where ad hoc advising strained operational tempo and highlighted the need for dedicated structures to build partner capacity without diverting combat brigades. On October 27, 2010, the Department of Defense issued Instruction 5000.68, which formalized SFA policy by defining it as activities to develop the capacity and capability of foreign and their supporting institutions to deter or defeat threats to stability. The instruction mandated integration of SFA into joint planning and , requiring commands to incorporate it into theater security cooperation plans and emphasizing measurable outcomes in partner self-sufficiency. Concurrently, the U.S. Army articulated SFA as a combination of tasks to enhance foreign ' capabilities, advocating for its doctrinal incorporation to support broader national objectives. Building on these foundations, the established the Security Force Assistance Brigades (SFABs) in as specialized, brigade-sized units composed of experienced officers and non-commissioned officers dedicated exclusively to advising, assisting, and enabling forces. The first SFAB activated on February 16, 2018, at , , followed by announcements for five active-component and one SFABs to professionalize advisory roles and alleviate burdens on conventional brigade combat teams. By May 2020, all six SFABs were operational, each tailored with enablers like , , and fires support to conduct SFA in permissive, semi-permissive, and contested environments. Army Techniques 3-96.1, published May 2, 2018, provided doctrinal guidance for SFAB operations, underscoring their role in fostering autonomy through advising and institutional . The Joint Center for International Security Force Assistance, operationalized in the early under U.S. Central Command and later joint auspices, further institutionalized SFA by developing standards, tactics, techniques, and procedures for cross-service application, ensuring among U.S. forces and allies. These developments reflected a doctrinal prioritizing SFA as a strategic tool for competition below armed conflict thresholds, with empirical focus on sustainability metrics like partner force readiness and reduced U.S. footprint requirements.

Operational Frameworks and Doctrine

Key Doctrinal Elements

Security force assistance (SFA) is defined in U.S. joint doctrine as Department of Defense activities that develop the capacity and capability of foreign and their supporting institutions to achieve security objectives aligned with U.S. national interests. This encompasses organizing, training, equipping, rebuilding or building institutions, and advising host nation (HN) forces across the competition continuum, from below armed to active hostilities. SFA emphasizes unified action integrating , diplomatic, and other U.S. government efforts, with the Department of Defense leading aspects under combatant commander theater campaign plans. Central to SFA doctrine are imperatives that guide effective implementation, including understanding the operational through assessments of political, , economic, social, , , physical , and time factors (PMESII-PT); ensuring of effort among joint, interagency, intergovernmental, and multinational partners; fostering HN to promote ; and prioritizing by linking to , , and economic viability. Additional imperatives stress building legitimacy via transparent processes and adherence, synchronizing efforts to counter narratives, providing effective leadership tailored to HN contexts, and avoiding harm through vetting and mitigation. These principles underscore causal linkages between institutional capacity-building and long-term , rejecting short-term tactical fixes in favor of enduring HN capabilities. Operationally, SFA employs an "OTERA" framework—organize, train, equip, rebuild/build, advise—to address capability gaps, with assessments using measures of performance and effectiveness to track progress quantitatively and qualitatively. Advising follows a teach-coach-advise progression, often via embedded teams at tactical levels (e.g., 12-person units for advising) and higher echelons, emphasizing , cultural proficiency, and parallel planning where HN forces lead with U.S. support. mandates persistent engagement, such as daily proximity advising (Level 1), to build and , while transitions occur incrementally based on HN readiness, ensuring interoperability and maintenance feasibility. In multinational contexts, aligns with these by prioritizing political primacy, comprehensive approaches integrating civilian-military efforts, and sustainability through "train-the-trainer" models.

Training and Advisory Methods

Training and advisory methods in security force assistance (SFA) encompass structured techniques to develop foreign security forces (FSF) capabilities, primarily through the organize, train, equip, rebuild/build, and advise (OTERA) framework. This approach integrates tactical advising with institutional capacity building, emphasizing host nation (HN) ownership and sustainability rather than direct U.S. command. U.S. doctrine, as outlined in Joint Doctrine Note 1-13, prioritizes assessments using measures of performance (MOP) and measures of effectiveness (MOE) to tailor methods to FSF gaps across executive, generating, and operating functions. Training methods follow a progressive "crawl-walk-run" model, beginning with individual skills such as marksmanship and , advancing to small unit leader via tactical exercises without troops, and culminating in collective tasks like squad-level drills and situational exercises. Advisors employ hands-on , leveraging instructors where possible, and incorporate after-action reviews (AARs) to reinforce lessons and adapt to FSF proficiency levels. Collective integrates military processes (MDMP) adapted for HN contexts, parallel where FSF leads with U.S. support, and train-the-trainer programs to foster . Equipping efforts focus on sustainable, maintainable systems with accompanying new to avoid dependency on unavailable . Advisory techniques emphasize teams that collocate with FSF units to build trust through daily interaction, subtle , and shared missions such as patrols or operations . Security Force Assistance Brigades (SFABs) deploy 12-person advisor teams (MATs), led by captains, at to levels, scaling to teams under majors for advising. Advising occurs in phased progression: teaching basic concepts interactively, during practice with guidance, and mentoring for independent , always influencing via relationships rather than authority. Specialized roles, including communications advisors for training and maintenance advisors for standard operating procedures (SOPs), address warfighting functions like and . Best practices stress cultural awareness, , and unity of effort through combined cells for functions like and , while advisors act as honest brokers assessing HN limitations transparently. Methods incorporate joint combined exchange training (JCET) for and Section 333 authorities for targeted training in areas like , ensuring alignment with combatant command objectives. Advisors maintain in ambiguous environments, prioritizing HN achievement of security goals over U.S.-directed outcomes, with sustainment coordinated externally to support long-term FSF viability.

Metrics of Effectiveness and Sustainability

Assessing the effectiveness of security force assistance (SFA) relies on , which quantify immediate outputs such as the number of trainees completing courses or transfers completed, and , which evaluate broader outcomes like enhanced partner operational independence or territorial control gains. are often tracked via systems like the Global-Theater Security Cooperation (G-TSCMIS), providing data on activity completion rates, but they risk overstating success by ignoring qualitative factors such as training quality or application in combat. MOEs incorporate (specific, measurable, attributable, realistic, time-bound) indicators aligned with doctrinal frameworks like DOTMLPF-P (, organization, training, , leadership and education, personnel, facilities, and ), aiming to link SFA inputs to intermediate objectives such as reduced reliance on external . Empirical evaluations, including those from U.S. security cooperation assessments, emphasize causal chains via theories of change, where effectiveness is scored on scales (e.g., 0-1, with a minimum of 0.5 for continuation), but attribution remains challenging due to variables like host-nation political instability. Sustainability metrics prioritize long-term viability, assessing (partner ability to integrate and maintain capabilities), (internal leadership and ), and handover success, such as gradual transitions to avoid dependency. Key components include viability (attainable goals and enduring practices), legitimacy ( reducing and enhancing ), and political subordination (effective civil-military relations ensuring non-interventionist forces). In practice, these are gauged via five-point assessment scales adapted from models, with sustainability faltering when metrics overlook host-nation will to fight or , as evidenced by high attrition rates (e.g., exceeding 3% monthly in ) despite extensive . Critiques from oversight bodies highlight systemic flaws in U.S. metrics, which often prioritize quantifiable inputs over verifiable outcomes, leading to misleading portrayals of progress in cases like , where $88 billion in assistance yielded forces unable to sustain control post-2021 withdrawal due to , poor , and insufficient internal cohesion rather than training deficits alone. reports acknowledge that without rigorous impact evaluations using comparison groups, effectiveness claims suffer from , as short-term gains rarely predict enduring stability absent host-nation reforms. Sustainable SFA thus demands integrated monitoring, such as after-action reviews and scenario-based , to validate causal impacts beyond surface-level indicators.

National and Institutional Implementations

United States Security Force Assistance Brigades

![Activation ceremony of the 1st Security Force Assistance Brigade]float-right The established Security Force Assistance Brigades (SFABs) between August 2017 and May 2020 to institutionalize security force assistance as a core competency, creating six specialized units—five active component and one —that focus exclusively on advising, assisting, and enabling partner nation security forces. These brigades emerged from lessons learned in and , where ad hoc advising by combat units diluted warfighting readiness and produced inconsistent outcomes in partner . SFABs enable persistent engagement with allies and partners by deploying advisor teams trained in language, cultural awareness, and tailored to foreign contexts, thereby freeing conventional brigade combat teams for decisive action roles. Each SFAB comprises approximately 800 personnel, predominantly experienced officers and non-commissioned officers selected for operational expertise, organized into headquarters, maneuver advisor teams (typically 10-12 soldiers), and support elements including , sustainment, and fires capabilities. Advisor teams operate at tactical levels, conducting assessments, training, and liaison to enhance partner forces' ability to plan, execute, and sustain operations independently. The 1st SFAB, activated on February 8, 2018, at (formerly Fort Benning), , exemplifies this structure, with subsequent activations including the 2nd SFAB at , ; 3rd at , ; 4th at , ; 5th at Joint Base Lewis-McChord, ; and 54th () headquartered in , . SFABs have conducted deployments across multiple theaters, with the 1st and 2nd SFABs rotating to starting in 2018 to advise Afghan National Defense and Security Forces amid U.S. drawdown efforts, though the rapid collapse of those forces in August highlighted limitations in achieving self-sustaining partner capabilities without indefinite U.S. overwatch. In , SFAB elements supported Combined Joint Task Force-Operation Inherent Resolve by training against ISIS remnants, contributing to territorial reconquest by 2017 but facing persistent challenges from corruption and sectarian divisions within partner units. Post-, SFABs shifted to great power competition theaters: the 4th SFAB in U.S. European Command enhanced allies' readiness against Russian threats; the 5th SFAB deployed to the for partner exercises; and the 54th SFAB supported operations in , including counter-narcotics training in and as of 2025. These efforts emphasize deterrence and over direct combat. Evaluations of SFAB effectiveness reveal strengths in professionalizing advising—such as specialized pipelines yielding more consistent —but persistent gaps in resourcing, authorities for operations under Title 10 or 22 U.S. Code, and integration with forces, which can limit impact in high-threat environments. A 2024 U.S. Institute of Peace assessment recommended structural reforms, including enhanced funding mechanisms and advisor retention incentives, to better align SFABs with objectives amid peer competitor threats. Despite these critiques, SFABs have demonstrated utility in low-intensity engagements, fostering long-term relationships that deter , as seen in rotations bolstering Ukraine's indirect support networks pre-2022 . Under oversight since 2021, SFABs continue evolving doctrine for multi-domain operations, prioritizing empirical metrics like partner force readiness scores over anecdotal success.

United Kingdom Formations and Approaches

The 's dedicated security force assistance (SFA) formation, the , was established in November 2021 as part of the British Army's Future Soldier reforms to institutionalize capacity-building for partner militaries. This brigade integrates expertise from across the Army, including battalions specialized in advisory roles, to deliver training, mentoring, and operational support aligned with UK strategic interests. By June 2024, units from the brigade, such as the 3rd Battalion, The Royal Regiment of Scotland, were actively conducting rehearsal drills and field training with partner forces, demonstrating its operational focus on enhancing tactical proficiency. In parallel, the brigade underwent a reorientation in 2024 toward a more combat-oriented role within the Land Special Operations Force, retaining SFA functions but prioritizing capabilities to intercept and engage adversaries while advising partners. It comprises four regular infantry battalions (1st Battalion, The Irish Guards; 1st Battalion, Royal Anglian Regiment; 3rd Battalion, The Rifles; 3rd Battalion, The Royal Regiment of Scotland), a reserve battalion (4th Battalion, Princess of Wales's Royal Regiment), and a specialist outreach group for tailored engagement. This structure enables persistent deployments, such as joint urban warfare training with U.S. partners in Kenya in February 2025, emphasizing interoperability and partner force readiness. Complementing the 11th Brigade, the Ranger Regiment—formed on 1 December 2021—provides elite, special operations-capable for high-risk SFA missions, including advising in "grey zone" conflicts below the threshold of . Operating under the , the regiment's four battalions focus on , , and capacity enhancement in contested environments, as evidenced by its November 2022 deployment alongside U.S. Forces to test equipment and tactics. This formation addresses gaps in traditional SFA by enabling advisers to accompany partners during operations, thereby sustaining assistance amid threats. UK SFA approaches are embedded in the International Defence Engagement Strategy, which prioritizes building partner security institutions to deter adversaries, counter threats, and secure influence without large-scale combat commitments. Activities span pre-conflict capacity development—such as leadership training and equipment familiarization—to post-conflict stabilization, often integrated with frameworks like Allied Joint Publication 3.16 for standardized advising and metrics. Emphasis is placed on sustainable outcomes through persistent presence, with evaluations drawing on empirical indicators like partner force retention rates and operational independence, though challenges persist in measuring long-term geopolitical impact. Prior to these formations, UK SFA relied on military advisory teams in operations like those in and from 2014–2019, focusing on tactical skills to support counter-terrorism efforts.

NATO and Allied Contributions

The Security Force Assistance Centre of Excellence (SFA COE), established in , , in 2016 and sponsored by , , and with as a contributing participant, serves as the Alliance's primary hub for advancing SFA capabilities. It focuses on development, specialized for and partner personnel, analysis, and interoperability enhancement to support stability in conflict and post-conflict environments. The center conducts courses, simulations, and research to refine SFA practices, emphasizing the generation and sustainment of partner security forces capable of addressing regional threats independently. NATO's SFA doctrine, outlined in Allied Joint Publication-3.16 (AJP-3.16, Edition B, Version 1), defines SFA as encompassing all activities that develop, improve, or directly the development of capable, accountable, and sustainable partner , applicable across strategic, operational, and tactical levels. This prioritizes tailored assistance, including advising, mentoring, , and institutional capacity-building, while integrating civil-military coordination to ensure long-term partner self-reliance. The doctrine evolved from lessons in operations like and , stressing measurable outcomes in force readiness and governance over indefinite external dependency. In , transitioned from combat operations under the (ISAF, 2001-2014) to a dedicated SFA role via the NATO Training Mission-Afghanistan (NTM-A, 2009-2014) and (RSM, 2015-2021), which provided training, advising, and institutional support to Afghan National Defence and Security Forces. These efforts emphasized leadership development, logistics sustainment, and tactics, enabling Afghan forces to assume primary security responsibilities by 2014, though sustainment challenges persisted post-withdrawal in August 2021. NATO's SFA in includes the NATO Training Mission-Iraq (NTM-I, 2004-2011), which assisted in rebuilding through officer professionalization, police training, and institutional reforms at the and elsewhere, followed by the non-combat Mission Iraq (NMI, launched 2018). NMI focuses on advising Iraqi ministries and training instructors in specialized areas such as counter-improvised explosive devices, , and equipment maintenance, with contributions from all Allies via personnel deployments, in-country or external training programs, financial support, and equipment donations to enhance Iraqi self-sufficiency against ISIS remnants. More recently, established the Security Assistance and Training for Ukraine (NSATU) command in 2024 to coordinate Allied military equipment provision and training for Ukrainian forces amid Russia's invasion, building on pre-existing SFA partnerships. This includes integration, tactical advising, and capacity enhancement through frameworks, with Allies committing over EUR 35 billion in security assistance by mid-2025, reflecting a collective Allied effort to bolster 's defense sustainability without direct combat involvement. NSATU draws on SFA expertise for doctrine alignment and . Allied contributions to NATO SFA extend through Partnership Training and Education Centres (PTECs) and individualized programs like Individual Partnership Action Plans, enabling non-member partners in the Western Balkans, Mediterranean, and beyond to access joint exercises and pre-deployment training for missions such as (KFOR). European Allies, including and , have provided specialized trainers and funding to these initiatives, complementing U.S. leadership while adhering to 's burden-sharing principles.

Case Studies and Empirical Examples

Notable Successes

One prominent example of successful security force assistance occurred during the British-led in the [Malayan Emergency](/page/Malayan Emergency) from 1948 to 1960, where advisors trained and expanded indigenous forces to isolate and defeat communist guerrillas. British military personnel, including units, focused on building the Malayan police and home guard, which grew to over 40,000 personnel by 1952, integrating them into "New Villages" resettlement programs that denied insurgents rural support and provided intelligence. This effort, combined with targeted operations, reduced insurgent strength from an estimated 8,000 fighters in 1951 to fewer than 500 active combatants by 1955, culminating in the emergency's declaration of success on July 31, 1960, with minimal British troop casualties relative to the scale—fewer than 2,000 total security force deaths against over 6,700 insurgents killed. In during the , U.S. advisory teams, capped at 55 military personnel under congressional limits, professionalized the Salvadoran armed forces through the Operational Planning and Assistance Training Team (OPATT) program from 1981 onward, emphasizing mobile infantry tactics, training, and to counter FMLN guerrillas. Advisors restructured units into battalions and regional commands, improving operational effectiveness; for instance, the Atlacatl , trained by U.S. personnel, conducted successful offensives like the 1981 counterattack at El Paraiso that halted insurgent advances. By 1984, government forces controlled 70% of territory and inflicted heavy losses on insurgents, contributing to the FMLN's shift to negotiations and the 1992 peace accords, with U.S. assistance totaling about $6 billion in enabling the government's survival without direct U.S. combat involvement. U.S. security force assistance under , initiated in 2000, bolstered Colombian military capabilities against FARC insurgents and narcotraffickers, training over 10,000 troops in counternarcotics battalions and providing helicopters and support that enhanced and mobility. From 2000 to 2015, U.S. aid exceeding $8 billion facilitated the of over 50,000 and guerrilla fighters, including FARC's 2016 peace deal, while homicide rates dropped 50% from 2002 peaks and cultivation stabilized after initial surges due to eradication efforts. Security improvements allowed economic growth and reduced FARC territorial control from 40% of in the to negligible post-2016, marking a rare case of sustained partner force autonomy in a protracted .

Prominent Failures

The rapid collapse of the National Defense and Security Forces (ANDSF) in August 2021 exemplified a major failure of U.S. security force assistance, despite over $88 billion invested in training and equipping since 2002. The ANDSF, numbering approximately 300,000 personnel on paper, disintegrated within weeks of the U.S. withdrawal, with units abandoning positions, equipment, and territory to advances, culminating in the fall of on August 15, 2021. Contributing factors included systemic corruption that eroded unit cohesion and , such as inflating payrolls by up to 40% in some units, and a heavy reliance on U.S. air support and contractors, which fostered dependency rather than self-sufficiency. Ethnic factionalism, particularly Pashtun dominance under President , alienated non-Pashtun troops, while morale plummeted due to the 2020 U.S.- Agreement, perceived as a betrayal that signaled abandonment. The Special Inspector General for Afghanistan Reconstruction (SIGAR), a congressionally mandated , attributed the failure partly to the government's inability to formulate a coherent strategy post-U.S. troop drawdown, compounded by deficits at senior levels. In Iraq, U.S. security force assistance efforts faltered dramatically with the Iraqi Security Forces' (ISF) collapse during the Islamic State's (ISIS) capture of Mosul on June 10, 2014, where roughly 30,000 ISF troops fled before a force of about 1,500 militants, abandoning vast quantities of U.S.-provided equipment. Despite $25 billion spent on training and arming the ISF since 2003, underlying issues included Prime Minister Nouri al-Maliki's sectarian policies, which marginalized Sunni units and fostered desertions, with some divisions losing up to 70% of personnel due to low motivation and corruption. Politicization of the military, including favoritism toward Shia militias and inadequate intelligence on ISIS movements, exacerbated the rout, as units prioritized self-preservation over defense. U.S. assessments prior to the fall had noted declining ISF readiness, with logistical breakdowns and poor leadership preventing effective SFA outcomes, echoing critiques of mismatched training that emphasized conventional tactics over counterinsurgency resilience. The Soviet Union's security force assistance to the Democratic Republic of Afghanistan from 1979 to 1989 represented another high-profile failure, as the Soviet-backed Afghan regime under Najibullah collapsed in 1992 after Moscow's withdrawal, despite deploying over 100,000 advisors and troops to train and bolster local forces. Key shortcomings involved underestimating tribal and ethnic resistances, leading to ineffective integration of Soviet doctrinal training into Afghan social structures, with regime forces suffering high desertion rates—estimated at 20-30% annually—and reliance on brutal repression rather than genuine capacity-building. The failure stemmed from misaligned strategic objectives, where Soviet advisors prioritized urban control over rural pacification, allowing mujahideen to erode government control, ultimately requiring $4-5 billion in annual subsidies that ceased post-1989, triggering the regime's fall. This case highlighted how external assistance without addressing internal political legitimacy often yields unsustainable forces, a pattern corroborated in declassified Soviet analyses.

Hybrid Outcomes in Ongoing Engagements

In the , initiated by Russia's full-scale invasion on February 24, 2022, U.S.-led security force assistance has delivered hybrid outcomes characterized by enhanced defensive capabilities alongside persistent strategic limitations. Multinational training programs, including those under and the Military Assistance Mission, have equipped over 51,000 Ukrainian personnel with skills in weaponry and tactics as of early 2025, enabling effective integration of provided systems like HIMARS and missiles. This support facilitated Ukraine's repulsion of initial Russian offensives, including the recapture of significant territory around in September 2022 and stabilization of fronts in and oblasts. However, the stalled against entrenched Russian positions, minefields, and adaptations, resulting in a protracted with estimated Ukrainian casualties exceeding 500,000 by mid-2025 and no decisive territorial breakthroughs. Analyses from defense think tanks note that while SFA improved and , challenges such as in —evidenced by documented diversions of —and acute manpower deficits have constrained offensive momentum and long-term , fostering on over $66.9 billion in U.S. disbursed by January 2025. In the , ongoing efforts against jihadist groups like JNIM and ISGS have yielded similarly mixed results from U.S. and security force assistance since 2014. Western programs, totaling more than $5.5 billion from the U.S. and €8 billion from the , have trained thousands of troops from , , and in and intelligence-sharing, yielding tactical successes such as localized clearances of insurgent strongholds in northern in 2022–2023. Yet, regional violence escalated dramatically, with militant Islamist activity comprising over half of 's total in 2024 and fatalities nearly tripling since 2020 to exceed 25,000 conflict deaths. Political disruptions, including coups in all three countries between 2020 and 2023, coupled with the influx of Russian (now Africa Corps) mercenaries offering transactional support without governance reforms, have eroded SFA impacts; U.S. force posture reductions in 2024 followed host-nation expulsions, leaving partner forces fragmented and violence unchecked. evaluations conclude that such assistance has produced minimal net reductions in , highlighting causal factors like weak state legitimacy and external proxy competition over internal capacity deficits alone. In , post-2017 SFA against remnants has maintained hybrid equilibria, with U.S. advisors embedded in enabling sustained operations that prevented major urban re-conquests by 2024. Over 2,500 U.S. personnel continue advisory roles under , contributing to the degradation of to under 10,000 fighters regionally. However, the parallel empowerment of Iran-aligned (PMF), integrated into state structures yet operating with de facto autonomy, has fostered "vicarious impunity" where abuses by PMF units—documented in over 100 civilian incidents since 2020—undermine unified command and fuel sectarian tensions, complicating full territorial stabilization amid ongoing low-level insurgencies. This duality reflects SFA's tactical bolstering of conventional forces against hybrid threats, tempered by unresolved political factionalism that perpetuates vulnerability to external influences.

Achievements and Strategic Impacts

Capacity-Building Victories

In , initiated in 2000, the provided over $10 billion in security assistance, including training for more than 200,000 Colombian military and police personnel, which contributed to the professionalization of the Colombian National Army and a significant decline in violence from insurgent groups like the (FARC). This effort enabled Colombian forces to regain territorial control, with homicide rates dropping from 70 per 100,000 inhabitants in 2002 to 25 per 100,000 by 2016, facilitating the FARC's demobilization under a peace accord signed on September 26, 2016. Although drug cultivation persisted, the enhanced operational capacity of partner forces demonstrated sustainable improvements in capabilities, as Colombian units increasingly conducted independent operations by the mid-2010s. The military intervention in , beginning with Operation Palliser in May 2000, involved training and restructuring the Sierra Leone Army (later Republic of Sierra Leone Armed Forces, RSLAF), transforming a disorganized force of approximately 14,000 personnel into a professional entity capable of securing the country post-civil war. advisors, numbering around 300-400 in initial phases, focused on basic skills, , and command structures, leading to the RSLAF's successful repulsion of advances and the war's end via the Peace Accord implementation by 2002. Long-term programs, such as the International Military Advisory and Training Team established in 2001, sustained these gains, enabling the RSLAF to handle independently by 2011 and contribute to regional stability without ongoing foreign combat presence. U.S. Special Operations Forces assistance to the from 2002 onward, under , built the capacity of the Armed Forces of the to combat the Group through joint training exercises and intelligence sharing, resulting in the group's operational defeat by 2019. This included equipping and advising Philippine units, which improved small-unit tactics and maritime interdiction, reducing 's strength from thousands to under 100 fighters and enabling Philippine forces to conduct autonomous operations in the southern islands. By 2014, U.S. advisors had transitioned to advisory roles only, with Philippine military effectiveness evidenced by a 90% decline in -initiated attacks in key areas, underscoring the transfer of sustainable skills.

Contributions to Regional Stability

Security force assistance (SFA) bolsters regional stability by enabling nations to independently counter internal insurgencies and external threats, thereby mitigating conflict diffusion and decreasing reliance on foreign combat deployments. This capacity-building fosters self-sustaining security architectures that deter aggression and promote cooperative regional security frameworks, as evidenced by U.S. Security Force Assistance Brigades (SFABs) tailored to specific areas of , enhancing capabilities against localized challenges. In , U.S. security sector assistance from the post-Cold War era onward has yielded small but statistically significant gains in stability indicators, such as reduced incidence of and improved metrics in recipient states, according to quantitative evaluations controlling for factors like aid volume and partner commitment. These effects, though modest, demonstrate SFA's potential to incrementally strengthen fragile states against transnational threats like jihadist insurgencies, preventing broader destabilization across porous borders. The U.S.-backed , launched in 2000 with over $10 billion in assistance through 2015, exemplifies SFA's stabilizing impact by professionalizing Colombian , which reclaimed over 90% of FARC-controlled territory and facilitated the group's 2016 peace accord, demobilizing approximately 13,000 combatants and halving national homicide rates from 2002 peaks. This reduced insurgent safe havens curbed narcotics trafficking and spillover violence into neighboring and , enhancing Andean regional security. Similarly, post-2014 SFA to Iraqi forces enabled the territorial defeat of by 2019, dismantling its and averting refugee crises and terror exports to and beyond.

Broader Geopolitical Benefits

Security force assistance (SFA) enables donor states to extend influence in contested regions without committing large expeditionary forces, thereby preserving resources for core defense priorities while shaping favorable security environments. By equipping and training partner militaries, SFA denies adversaries like and opportunities to expand footholds through their own assistance programs, as seen in U.S. efforts to counter Beijing's diplomacy in the and Africa's . This indirect approach has historically amplified geopolitical leverage, such as during the when U.S. advising in and helped contain Soviet expansion by fostering aligned security partners capable of independent action. A core benefit lies in building and trust among regional allies, which facilitates collective defense mechanisms and burden-sharing in multinational operations. For instance, U.S. SFA programs have enhanced partners' capacities along eastern flanks, contributing to deterrence against Russian aggression post-2014 Crimea annexation by enabling rapid partner-led responses integrated with alliance structures. This fosters long-term diplomatic alignment, as strengthened partners are more likely to support donor objectives in forums like the or bilateral trade pacts, reducing isolation risks in multipolar rivalries. Empirical data from U.S. Department of Defense assessments indicate that SFA investments, totaling over $10 billion annually across global programs as of , yield multipliers in partner autonomy that offset direct U.S. deployments. In competition, SFA serves as a spoiling mechanism against rivals' strategic gains, allowing donors to invest cost-effectively in partners who address localized threats—such as insurgencies or incursions—that could otherwise draw in major powers. U.S. advising in the since 2016, for example, has bolstered against Chinese assertiveness in the , enhancing regional coalitions without escalating to confrontation. Such outcomes extend to economic dimensions, as stable partners secured through SFA open avenues for resource access and projects, countering initiatives like China's Belt and Road by tying security ties to developmental . Overall, these benefits accrue from SFA's emphasis on sustainable capacity over transient interventions, promoting a network of resilient allies that amplifies donor strategic depth.

Criticisms and Analytical Challenges

Structural and Bureaucratic Shortcomings

The U.S. (DOD) and Department of State lack a defined joint planning process for security cooperation activities under Section 333 authority, resulting in fragmented efforts to build partner capacity through train-and-equip projects. This structural gap has led to inconsistent State Department involvement, as roles and timelines remain undefined, pressuring officials to approve proposals without adequate review time for alignment with U.S. priorities or partner absorption capabilities. From fiscal years 2018 to 2021, 42 of 46 DOD project proposals omitted essential elements such as sustainment plans, assessments, or measurable objectives, undermining long-term effectiveness. Bureaucratic hurdles exacerbate these issues, including insufficient training for State Department personnel on security cooperation, which limits overseas officials' ability to contribute meaningfully to planning. Delayed State inputs during detailed proposal development further risk misaligned initiatives, while congressional notifications often exclude critical details on sustainment and capacity, complicating oversight. In parallel, the (FMS) process, essential for equipping partner forces, suffers from outdated regulations and excessive bureaucracy, causing multi-year delays in deliveries that hinder operational readiness. These delays persisted despite $5.6 billion allocated for Section 333 projects from fiscal years 2018 to 2022, highlighting systemic inefficiencies in resource allocation. Advisor deployments face structural discontinuities from high rotation rates, typically 6-12 months, which prevent sustained relationships and institutional critical for SFA success. Security Force Assistance Brigades (SFABs), established to professionalize advising, encountered manning shortages and recruiting difficulties, depriving units of experienced noncommissioned officers and limiting specialized training beyond basic courses. DoD doctrine's emphasis on rapport-building persuasion, while de-emphasizing incentives or conditionality, reflects a bureaucratic aversion to perceived , fostering ineffective metrics focused on minor concessions rather than verifiable capability gains—as evidenced by the Afghan Army's despite $83 billion in assistance from 2001 to 2021.

Cultural and Political Mismatches

Cultural differences between assisting nations and partner forces often undermine security force assistance efforts by creating barriers to effective and . Foreign cultural attributes, such as divergent views on , , and operational , can impede the adoption of Western-style doctrines, leading to persistent gaps in performance. In , for instance, tribal affiliations and local power dynamics frequently superseded national cohesion, resulting in unreliable partner units prone to or internal fractures despite years of advising. This cultural incompatibility contributed to over 26 documented green-on-blue attacks by forces against members between 2007 and 2011, eroding trust and operational effectiveness. Political mismatches exacerbate these issues when U.S. strategic objectives clash with the recipient state's structures or incentives. Assistance programs tend to concentrate on states with the weakest political institutions, an dynamic that amplifies risks of failure as partners prioritize short-term survival over long-term . In , despite extensive training, the army's 2014 collapse against stemmed from underlying political fragility, including sectarian divisions and corruption, which advising could not resolve without aligned domestic reforms. Similarly, in , cultural and political disconnects—such as mismatched motivations between U.S.-backed centralized command and guerrilla-oriented resistance—deepened mistrust and contributed to advising shortfalls. Without congruence between donor aims and host-nation politics, SFA risks bolstering forces that either fracture under pressure or pursue agendas antithetical to the provider's interests.

Resource Allocation Inefficiencies

Security force assistance (SFA) programs frequently exhibit resource allocation inefficiencies stemming from fragmented oversight, mismatched equipment provisioning, and insufficient accountability mechanisms, resulting in substantial financial waste without commensurate improvements in partner capabilities. In , the allocated approximately $83 billion from 2002 to 2021 toward training and equipping the National Defense and Security Forces (ANDSF), yet these investments yielded limited , as evidenced by the ANDSF's rapid disintegration following the U.S. withdrawal in August 2021. A notable instance involved an additional $28 million expenditure on uniforms ill-suited to 's , driven by the aesthetic preferences of a single general rather than operational efficacy, highlighting decision-making detached from strategic needs. Further inefficiencies arose from corruption and poor sustainment planning, with the Special Inspector General for Afghanistan Reconstruction (SIGAR) identifying $19 billion in waste, fraud, and abuse across $63 billion of reviewed reconstruction funds, including SFA-related expenditures where equipment often went unused or was diverted. In , SFA efforts post-2003 faced similar issues, with the Provisional Authority's mixed outcomes in rebuilding institutions attributed to uncoordinated resource distribution and inadequate integration of U.S. aid into Iraqi budgetary processes, leading to over-reliance on external funding without building endogenous capacity. (GAO) assessments have underscored broader challenges in U.S. assistance, including fragmented across agencies that duplicates efforts and hampers cost-effective allocation, as seen in evaluations from fiscal years 2018 to 2024 where monitoring gaps allowed resources to be misdirected. These patterns reflect systemic flaws, such as prioritizing short-term metrics like unit training numbers over long-term viability, exacerbated by limited of supplemental appropriations that bypassed standard budgeting scrutiny. In both theaters, resources were often funneled through contractors with inadequate performance tracking, contributing to inflated costs—for instance, $3.74 billion on aviation fuel alone amid broader sustainment failures. Such misallocations not only diminished strategic returns but also strained U.S. budgets, prompting calls for reformed doctrines emphasizing vetted, outcome-based funding tied to verifiable partner reforms.

Controversies and Debates

Ethical Dilemmas in Advisory Roles

Military advisors in security force assistance (SFA) roles frequently navigate tensions between operational imperatives and adherence to standards, particularly when partner forces exhibit practices incompatible with international norms. The U.S. , codified in Section 620M of the of 1961 and paralleled in Department of Defense provisions, bars assistance to foreign security units credibly implicated in gross violations such as extrajudicial killings or , requiring of over 160,000 candidates annually. , however, presents dilemmas: advisors must assess credible evidence amid incomplete intelligence, balancing the risk of complicity against mission disruption, with remediation contingent on host-nation investigations that often falter due to weak mechanisms. This framework underscores causal challenges, as training intended to instill rule-of-law principles can inadvertently legitimize abusive units if gaps persist, prioritizing short-term capacity over long-term ethical alignment. In Afghanistan, U.S. advisors confronted acute ethical conflicts over partner forces' endemic abuses, including "bacha bazi"—the sexual exploitation of boys by Afghan security personnel—which persisted despite explicit U.S. policy prohibitions under the 2017 National Defense Authorization Act barring support for perpetrators. Advisors often deferred confrontation to preserve rapport and operational effectiveness against the Taliban, fostering moral injury among U.S. personnel who witnessed unchecked predation yet prioritized counterinsurgency gains; reports indicate such tolerance alienated local populations and fueled insurgent recruitment. Similarly, divergent moral codes exacerbated dilemmas, as enforcing U.S. standards on issues like civilian targeting required navigating cultural relativism without undermining cohesion, with surveys of U.S.-trained forces showing reduced human rights adherence under conflicting orders. Iraq provides another case, where U.S.-trained committed documented sectarian abuses post-2003, including in detention facilities, prompting advisors to grapple with whether to suspend training amid strategic pressures to combat . Despite instruction, structural issues like and led to persistent violations, raising questions of advisor : continued engagement risked enabling harm, while withdrawal could cede ground to adversaries, as evidenced by the 2014 Mosul collapse partly attributed to eroded trust from abuses. These scenarios highlight a recurring causal : SFA's emphasis on partner often dilutes oversight, amplifying ethical hazards when clashes with host-nation , as non-state surrogates in conflicts like further complicate complicity risks through abandonment post-partnership.

Accountability for Partner Force Abuses

The Leahy Laws, enacted in the 1990s and codified in annual appropriations acts, prohibit U.S. assistance to foreign security force units credibly implicated in gross violations, such as extrajudicial killings, , or , unless the partner government investigates and remediates the issue. These provisions, named after Senator , apply separately to the Department of State (for foreign military financing and International Military Education and Training) and the Department of Defense (for programs like security force assistance), requiring pre-assistance based on official records, intelligence, and credible NGO reports. Vetting aims to prevent U.S. complicity in abuses but faces enforcement gaps, as determinations often rely on incomplete data from conflict zones where monitoring is limited. Implementation challenges include difficulties in attributing abuses to specific units amid decentralized command structures, partner governments' reluctance to prosecute their own forces, and the scale of assistance programs involving thousands of personnel. For instance, a 2025 report highlighted delays in State Department responses to civilian harm allegations from partner forces, noting that while some units are suspended, remediation rarely leads to due to weak foreign judicial systems. Critics, including organizations, argue that strategic imperatives often override strict enforcement, allowing tainted units to retain aid if abuses are deemed unconfirmed or isolated. In Iraq, U.S.-trained elements of the 16th Division of the Iraqi Army were implicated in the extrajudicial execution of at least 72 prisoners, including ISIS suspects, during the 2017 Mosul offensive, with bodies found in mass graves bearing execution-style wounds. Despite Leahy vetting, the incidents underscored vetting limitations, as the division had received U.S. training and equipment shortly before; no immediate U.S. aid cutoff was reported, though investigations were urged. Similarly, in Afghanistan, a 2018 Special Inspector General for Afghanistan Reconstruction audit found the Pentagon continued funding Afghan National Defense and Security Forces units despite credible evidence of child sexual abuse by members, violating Leahy standards; of 5,753 vetted individuals, only a fraction were flagged, with remediation often inadequate due to cultural tolerance of "bacha bazi" practices among commanders. The Defense Department withheld details from Congress, citing operational sensitivities, leading to accusations of impunity for U.S.-backed warlords. These cases illustrate broader tensions: while Leahy sanctions have disqualified units—such as commandos in 2017 for night raid abuses—effectiveness is hampered by non-transparent processes and the risk that withholding aid undermines goals without deterring abuses rooted in partner forces' internal dynamics. U.S. officials maintain that engagement enables influence for reform, but empirical outcomes show persistent violations, as documented in State Department reports, prompting calls for enhanced and third-party monitoring.

Deterrence and Strategic Miscalculations

Security force assistance (SFA) is frequently employed to bolster partner nations' military capabilities as a means of deterrence, aiming to raise the costs of for adversaries by creating resilient allied forces capable of independent defense. However, this approach has repeatedly led to strategic miscalculations, where assisting states overestimate the durability and motivation of partner forces, fostering illusions of that collapse under pressure. Empirical evidence from post-conflict environments reveals that SFA often fails to instill the institutional cohesion or political will necessary for sustained deterrence, as partners may prioritize short-term resource extraction over long-term operational readiness, leading donors to misjudge thresholds and adversary resolve. In , two decades of U.S.-led SFA, totaling over $88 billion in training, equipping, and advising the Afghan National Defense and Security Forces (ANDSF), culminated in a rapid collapse in August 2021 following the U.S. withdrawal. U.S. planners miscalculated the ANDSF's dependence on external enablers like air support and logistics, assuming that numerical superiority—peaking at 352,000 personnel—and SFA investments would deter advances; instead, widespread corruption, including "" inflating payrolls by up to 40%, eroded unit cohesion, resulting in provinces falling in days without significant combat. This strategic error not only negated deterrence against the but also signaled vulnerability to regional actors, as the ANDSF abandoned $7 billion in U.S.-provided equipment, enabling rapid insurgent consolidation. Similarly, in , SFA efforts post-2003, involving billions in training and $25 billion in equipment by , failed to deter the Islamic State's () offensive, exemplified by the collapse of Iraqi forces in on June 10, , where 30,000 troops fled against 800-2,500 ISIS fighters. Miscalculations stemmed from overlooking endemic issues like sectarian divisions, poor leadership, and motivational deficits—exacerbated by siphoning funds—despite U.S. warnings of declining ; this led to the abandonment of vast stockpiles, including 2,300 Humvees and 40 tanks, necessitating renewed U.S. intervention via starting in . Such breakdowns undermined deterrence signaling, as ISIS exploited perceived Iraqi fragility to seize one-third of the country by mid-. These cases illustrate a recurring causal pattern in SFA-driven deterrence: donors' focus on quantifiable metrics like troop numbers and obscures qualitative failures in partner and warfighting culture, inviting adversary opportunism and eroding credibility. Analyses from government oversight bodies highlight that without addressing root causes like of resources, SFA reinforces brittle structures prone to rapid dissolution, prompting strategic reassessments toward more conditional assistance tied to verifiable reforms.

Recent Developments and Future Prospects

Post-Afghanistan Reforms

Following the collapse of the Afghan National Defense and Security Forces in August 2021, which occurred despite approximately $88 billion in U.S. security sector assistance from 2002 to 2021, the Department of Defense (DOD) and undertook reviews to rectify deficiencies in security force assistance (SFA), including fragmented responsibility, inadequate planning, and unsustainable equipping practices. These efforts emphasized professionalizing advisors through mandatory certification training, extended deployment durations beyond the prior 6-12 month norms to build sustained relationships, and predeployment preparation tailored to host-nation contexts. Organizational adaptations included the expansion of the Ministry of Defense Advisors (MODA) program, integrating civilian specialists with military personnel for holistic ministry-level advising, and refinements to Security Force Assistance Brigades (SFABs)—initially stood up in 2017—to enable persistent, non-combat engagements focused on partner self-reliance rather than dependency-creating support. The U.S. Army addressed prior SFA shortcomings, such as advisor assignments during the , by institutionalizing permanent SFA formations and prioritizing units with doctrinal expertise in training and enabling host forces. Doctrinal shifts post-2021 stressed aligning SFA with host-nation political incentives and governance capacity, rejecting open-ended financing that eroded forces' motivation for self-sustainment, and incorporating rigorous to track outcomes beyond inputs like equipment delivery. Proposals emerged for a dedicated advising career track across the joint force, rewarding linguistic, cultural, and operational proficiency to elevate SFA as a strategic competency, alongside calls for a functional command to unify interagency efforts and reduce turnover in long-term missions. In the context of , reformed SFA prioritizes selective partnerships with aligned actors to enhance deterrence and access, drawing on Afghanistan's failures to avoid over-investment in unmotivated forces while leveraging advisors for influence in proxy dynamics and alliance-building. These changes reflect a broader pivot from large-scale reconstruction to targeted capacity-building, informed by oversight reports highlighting the need for enduring strategies over tactical expediency.

Applications in Contemporary Conflicts

In , the has applied security force assistance to enhance the capabilities of units combating al-Shabaab, an affiliate active since the mid-2000s. Under a 2017 agreement, the committed to recruiting, training, equipping, and mentoring approximately 3,000 personnel for the elite , focusing on operations and building sustainable forces. Between 2010 and 2020, this effort included over $500 million in direct assistance, encompassing advisory support from special operations forces to improve tactical proficiency and operational coordination against the group's attacks, which have killed thousands and displaced millions. Africa Command has supplemented these ground efforts with airstrikes in collective of Somali forces, such as the August 2025 strike targeting al-Shabaab militants. In the Philippines, security force assistance has targeted ISIS-affiliated groups, including during the 2017 Siege of Marawi, where Islamist militants seized the city and held it for five months, resulting in over 1,200 deaths. US special operations forces provided non-combat advisory support, including intelligence sharing and , to Philippine troops, enabling the eventual recapture of the city on October 23, 2017. Post-siege, ongoing US-Philippine cooperation has emphasized for Philippine to counter remnants of groups like and the Maute organization, which pledged allegiance to and continue low-level attacks in the southern regions. This assistance aligns with broader objectives, leveraging joint exercises and equipment transfers to address transnational threats without large-scale US troop commitments. Amid the 2022 , security force assistance has manifested primarily through external training programs rather than in-country advising, due to the high-risk combat environment. As of February 2024, over 30 countries, led by the , trained approximately 116,000 Ukrainian personnel outside the country, with the accounting for about 16% or roughly 18,560 trainees focused on weapons handling, tactics, and sustainment. The , authorized by Congress, funds these efforts to build long-term defensive capacity, including integration of Western systems like HIMARS and missiles, though effectiveness depends on Ukraine's internal absorption and challenges. Security Force Assistance Brigades have supported related European deployments, such as the 4th SFAB's 2021 rotation to advise allies amid heightened tensions.

Evolving Doctrines Amid Great Power Competition

U.S. military doctrines for security force assistance (SFA) have shifted significantly since the 2018 National Defense Strategy, which prioritized great power competition with and over operations. This evolution emphasizes building partner militaries' capabilities to deter aggression, counter adversarial influence, and operate in multi-domain environments, rather than solely focusing on internal stability. The U.S. Army's Security Force Assistance Brigades (SFABs), first activated in with the 1st SFAB standing up on December 7, , represent a dedicated structure for this purpose, deploying specialized advisor teams to enhance partners' and resilience against peer competitors. In response to Chinese and Russian military assistance programs—such as China's support in and the , and Russia's deployments—U.S. SFA now integrates with broader campaigns of integrated deterrence. SFABs perform core functions including assessment, advising, liaison, and support across the continuum, from peacetime engagements to crisis response, enabling partners to disrupt adversary and hybrid threats. For instance, in the , SFAB rotations have focused on training Philippine and forces for high-end operations to counter . Doctrinal updates, informed by post-Afghanistan lessons, prioritize scalable advising models that align with (JADC2) concepts, allowing partners to contribute to U.S.-led coalitions against great powers. The Army's SFA triad—comprising SFABs, forces, and security cooperation activities—provides combatant commanders flexible options to build influence and spoil adversarial gains, as evidenced by expanded SFAB deployments in following Russia's 2022 invasion of . Evaluations indicate SFABs have adapted by incorporating language skills, cultural expertise, and advanced warfighting tactics, though challenges persist in measuring long-term partner autonomy amid resource constraints. This doctrinal pivot underscores SFA's role in strategic , aiming to multiply U.S. force projection without direct commitments.
