Based at Norton Manor Camp near , , 40 Commando continues to train for global threats under the evolving structure, emphasizing innovation in sea-raiding and advanced technologies.

Overview and Role

Formation and Mandate

40 Commando was established on 14 February 1942 at , initially designated as the Royal Marine Commando and comprising volunteers from existing units organized into A, B, and X companies. This formation marked the creation of the first dedicated commando unit, intended to conduct raiding and reconnaissance operations in support of Allied amphibious efforts during . The unit was briefly redesignated as Royal Marine Commando (A) before adopting the numerical title No. 40 Royal Marine Commando on 12 October 1942. Following its initial deployment, 40 Commando participated in the on 19 August 1942, suffering heavy casualties but gaining valuable experience in . The unit was disbanded in October 1945 after service in and other theaters but was reformed on 16 March 1947 in as part of to maintain the Royal Marines' commando capability amid post-war commitments in . The mandate of 40 Commando centers on serving as a battalion within the UK's Force, specializing in rapid reaction forces for amphibious, , mountain, and . It maintains readiness for global deployment at short notice to execute sea-based raiding, , and crisis response missions, while also supporting and disaster relief operations in extreme environments. This role emphasizes high mobility, adaptability, and integration with naval assets to address diverse threats from littoral zones to inland objectives.

Current Organization and Structure

40 Commando operates as a battalion-sized formation within the , comprising approximately 500 personnel held at high readiness for global crisis response and expeditionary operations. Under the transformation initiated in the mid-2010s, the unit has been restructured to prioritize littoral maneuver, with its core consisting of four strike companies designed to form Littoral Strike Units. These companies integrate reconnaissance, raiding, and precision strike elements, enabling scalable task groups for amphibious assaults, special operations-capable missions, and integration with allied forces such as the . The strike companies are supported by specialized enablers, including logistics, , and base support functions, allowing sustained operations without reliance on fixed infrastructure. This modular structure facilitates embarkation on amphibious platforms like the Albion-class landing platform docks, contributing to persistent Littoral Response Groups for the Euro-Atlantic and theaters. 40 Commando's companies emphasize adaptability to extreme environments, with a doctrinal focus on jungle and to complement broader Force capabilities. Headquartered at Norton Manor Camp in , , the unit maintains a command company for , planning, and coordination, ensuring rapid force generation for tasks ranging from humanitarian assistance to high-intensity combat. As of 2025, this organization reflects ongoing adaptations to peer adversary threats, emphasizing distributed lethality and reduced logistical footprints over traditional maneuvers.

Capabilities and Equipment

Training and Specialization

Personnel assigned to 40 Commando complete the ' 32-week Commando Course at the Commando Training Centre (CTCRM) in Lympstone, , which encompasses individual skills training (weeks 1-10), team and section skills (weeks 11-15), troop and urban operations (weeks 16-24), and final tests including the Endurance Course, Nine Mile Speed March, Tarzan Assault Course, and 30 Miler. This program, the longest infantry basic training among forces, emphasizes physical endurance, weapons handling, fieldcraft, and amphibious tactics to forge versatile commandos capable of independent action. Post-initial training, 40 Commando Marines specialize in littoral maneuver and within the UK Commando Force framework, focusing on rapid deployment for raiding, amphibious assaults, and operations in austere environments. Unit training includes scenario-based exercises simulating peer-adversary threats, such as deep and strike missions in contested spaces, often integrated with joint forces. Specializations encompass , desert operations, survival, and urban combat, with Marines qualifying in skills like combat assault breaching and support. Recent exercises highlight this adaptability: in May 2023, approximately 140 troops from Charlie Company conducted jungle patrolling, navigation, break-contact drills, and ambushes in to prepare for contingencies. Similarly, in December 2020, Charlie Company teams trained in the on maneuver under fire and integration, while January 2023 drills refined ambush tactics in dense terrain. These rotations ensure proficiency across terrains, enabling 40 Commando to deploy globally at short notice against diverse threats.

Weapons and Support Systems

The primary individual weapon for in 40 Commando is the L403A1 (KS-1) , a 5.56mm selective-fire adopted in 2023 as the Alternative Individual Weapon to supplement or replace older variants in Commando Force units, including 40 and , with over 1,000 units delivered for enhanced close-quarters and maneuverability in littoral environments. Complementing this, some elements have transitioned to the MCX (L403A1 AWS variant) as a primary close-combat , emphasizing modularity and suppressibility for tasks. For precision engagements, designated marksmen employ the chambered in 7.62mm, while sniper teams utilize the L115A3 or similar long-range rifles capable of effective fire beyond 1,500 meters, though the Royal Marines also field the in for targets exceeding 1 km with adjustable stocks and bipods. Support weapons include the L110A2 (5.56mm) for squad automatic fire and the L7A2 general-purpose machine gun (7.62mm) for sustained suppression, alongside the L134A1 Heavy Machine Gun () for vehicle-mounted or anti-materiel roles. Heavy support systems encompass indirect fire from 81mm s, operated by two-man teams delivering high-explosive, smoke, or illumination rounds up to 5,650 meters, as demonstrated by 40 's mortar platoons in recent exercises like PREDATORS RUN. Anti-armor capabilities are provided by the Next Generation Light Anti-Structure Weapon (), a man-portable 150mm with 1 km and predictive guidance for defeating light vehicles and bunkers, and the missile system, a medium-range anti-tank guided weapon transportable by one , capable of top-attack profiles against armored threats including tanks and low-flying helicopters. Each unit, including 40 , maintains an Anti-Tank Troop with at least six teams for integrated platoon-level support. launchers such as the L17A2 (40mm underslung) augment small-arms fire for area suppression and anti-personnel effects.

Historical Operations

World War II Engagements

40 Commando, initially designated as A Commando and formed in February 1942 from volunteers of the Royal Marines, conducted its debut operation during the (Operation Jubilee) on 19 August 1942. The unit, comprising approximately 370 men under Joseph Picton Phillips, was tasked with landing east of the port to neutralize coastal batteries and secure the harbor area for follow-on forces. Facing intense German defenses, including machine-gun fire and artillery from elevated positions, the commandos encountered immediate setbacks with under heavy suppression; many were killed or captured during the assault, and the objective was not achieved. Phillips was , and the raid resulted in near-total losses for the commando element, highlighting deficiencies in amphibious tactics that informed later Allied planning. In the Italian Campaign, 40 Commando participated in Operation Devon, an amphibious landing at on the Adriatic coast on 3 October 1943, alongside and elements of the Special Raiding Squadron. The force of roughly 500 commandos landed under cover of darkness north of the Biferno River mouth, rapidly advancing inland to seize the town and airfield before German reinforcements could consolidate. By dawn, was captured with minimal initial opposition, enabling Allied troops to establish a bridgehead that disrupted German supply lines; however, subsequent counterattacks by the German 1st Parachute Division tested the position until relieved by the 8th Indian Infantry Division on 6 October. The operation succeeded in outflanking the German Gustav Line defenses, though 40 Commando suffered casualties from the ensuing fighting. The unit continued operations in , engaging on the River front in January 1944 before reinforcing the beachhead (Operation Shingle) by late February. At , 40 Commando conducted aggressive patrols and minor assaults to probe and expand the perimeter against entrenched German forces, including elements of the 26th Panzer Division, amid stagnant conditions that pinned Allied troops for months. These actions involved small-scale raids to disrupt enemy positions and gather intelligence, contributing to the gradual breakout in May 1944, though the commandos incurred losses from artillery and counter-patrols, with some personnel captured. Throughout 1943–1945, 40 Commando supported Adriatic operations, including raids and landings along the Dalmatian coast and in to harass garrisons and support partisan forces, as part of broader efforts to tie down German reserves. In the Spring 1945 offensive, the unit executed a during at Lake Comacchio on 1–2 April, crossing the Reno River to secure its northern bank and destroy infrastructure, such as a power plant on 11 April, diverting German attention from the main 8th Army thrust. Supported by Italian partisans, this maneuver involved amphibious elements navigating shallow lagoons and canals against fortified positions, facilitating the advance into the and hastening the Italian theater's conclusion, with 40 Commando sustaining further casualties in .

Post-War Counter-Insurgencies


Following the Second World War, 40 Commando engaged in counter-insurgency operations across multiple theaters, focusing on securing British interests against guerrilla threats. In the Malayan Emergency (1948–1960), elements of the unit supported 3 Commando Brigade in operations against communist insurgents on the Malay Peninsula, contributing to jungle patrols and security efforts that helped suppress the uprising.
During the Cyprus Emergency (1955–1959), 40 Commando, based in , deployed to the island to counter terrorist activities seeking with ; from February 1957 to July 1958, the unit conducted patrols and cordon operations amid ethnic tensions between and . In the (1963–1966), 40 Commando undertook six tours in , including operations in from July to December 1964 as part of the Tawau Assault Group, where they repelled Indonesian incursions through cross-border raids and fortified border defenses against irregular forces. For the Aden Emergency (1963–1967), 40 Commando operated in the , particularly in the Dhala region in 1963, providing support to the Federal against dissident tribesmen and nationalist insurgents through patrols and fortified positions to maintain order ahead of British withdrawal.

Cold War Conflicts

In November 1956, during Operation Musketeer—the Anglo-French-Israeli intervention in the —40 Commando conducted amphibious landings at , , alongside , to seize control of the Zone following its nationalization by President . On 6 November, supported by tanks from the Royal Tank Regiment, elements of 40 Commando advanced from Sierra Red beach into the city center, capturing key objectives including Navy House, a fortified Egyptian naval facility, amid urban fighting against Egyptian forces and irregulars. The operation faced logistical challenges, including limited air support due to political constraints from the and , but 40 Commando secured their assigned sectors with minimal casualties, contributing to the rapid initial gains before a ceasefire on 7 November halted further advances. The unit's most prominent Cold War combat deployment occurred during the in 1982, as part of in Operation Corporate, the British response to Argentina's of the on 2 April. On 21 May, troops from 40 Commando were among the first to land at San Carlos Water, establishing and defending the beachhead at Ajax Bay against Argentine air attacks, which inflicted heavy losses on British shipping but failed to dislodge the marines. Over the following weeks, the commando yomped approximately 56 miles across the islands' terrain, enduring harsh weather and enemy fire, before participating in the final offensive on Port Stanley; this included a daylight helicopter assault on 11–12 June against Argentine positions on Sapper Hill, one of the war's few such operations, helping to force the surrender of approximately 11,000 Argentine troops on 14 June. 40 Commando suffered three fatalities and several wounded during the campaign, earning praise for their endurance and role in reclaiming the islands without reliance on sustained armored support. Beyond these engagements, 40 Commando conducted operations to safeguard British interests in volatile regions, such as a 1964 deployment to the Congo during the , where the unit evacuated civilians and protected assets amid proxy conflicts between superpowers. These missions underscored the commando's amphibious expertise in rapid response scenarios, though they involved limited direct combat compared to and the Falklands.

Post-Cold War Deployments

In 1991, 40 Commando deployed to northern as part of to secure the safety of fleeing by Saddam Hussein's forces and to support regional stabilization efforts. The unit conducted patrols and established secure zones amid harsh mountainous terrain, contributing to the establishment of a safe haven until July 1991. Following this, 40 Commando undertook multiple tours in during ' later phases, focusing on counter-terrorism operations, riot control, and community policing in volatile areas. These deployments, spanning the , involved four rotations emphasizing intelligence-led patrolling and vehicle checkpoints to disrupt activities. The unit participated in the 2001 invasion of Afghanistan, becoming the first British ground force to deploy, securing near on 13 November and subsequently conducting urban patrols in the capital to counter remnants. Elements integrated with for mountain operations targeting positions. During Operation Telic in 2003, 40 Commando executed an amphibious helicopter assault on the on 20 March, landing via helicopters as the initial conventional coalition troops in . The operation secured vital oil infrastructure, preventing sabotage, and cleared Iraqi coastal defenses amid chemical threat risks, advancing inland to link with ground forces. 40 Commando returned to multiple times, including a 2007 deployment under 52 Infantry Brigade in for counter-insurgency patrols and base security. In April 2010, as part of 12, the unit operated in district, engaging in intense against forces, mentoring Afghan troops, and dismantling improvised explosive devices until October. These efforts supported provincial reconstruction amid high casualty rates from ambushes and booby traps. The unit also contributed to special forces support groups in Afghanistan, providing firepower and logistics for high-risk raids from 2001 onward. Deployments continued until the 2013 withdrawal of combat troops, with 40 Commando involved in the final Marine rotations securing key areas.

Controversies and Criticisms

Malayan Emergency Incidents

During the , members of 40 Commando were ed posing with the severed head of a Malayan National Liberation Army (MNLA) guerrilla killed in combat, an image that contributed to the British Malayan headhunting scandal. The practice of decapitating insurgents emerged as a means to verify kills in dense jungle terrain, where bodies were often unrecoverable, and to confirm identities for payments and purposes, amid broader counter-insurgency tactics employed by British forces. The , depicting soldiers in a 40 Commando base handling the head, was published on the front page of the on 28 under the headline "This is the war in Malaya," sparking public outrage in Britain and accusations of barbarism. The scandal highlighted tensions between operational necessities and ethical concerns, with critics, including Labour MPs, condemning the imagery as evidence of dehumanizing warfare, while military defenders argued it prevented fraudulent claims and aided in disrupting the communist insurgency's supply networks. An official inquiry followed, leading to orders from High Commissioner General Sir Gerald Templer prohibiting head-taking except under strict supervision, though the incident underscored the brutal realities of jungle counter-guerrilla operations where 40 Commando conducted patrols and ambushes in areas like Perak. No prosecutions resulted directly from the 40 Commando image, but it fueled parliamentary debates on colonial conduct and contributed to policy shifts emphasizing "hearts and minds" strategies over such visceral proofs of engagement.

Operational and Training Disputes

In 2005, a video emerged depicting an initiation ceremony for new recruits to 40 Commando at their base in , , showing marines engaged in naked wrestling in mud, being pelted with eggs, and other humiliations described by participants as "letting off steam." The maintained that such activities did not constitute and were not indicative of unit policy, despite public and media scrutiny prompting a criminal into allegations of violent within units, including footage of a marine being beaten unconscious. Further incidents in 2016 involved three marines from 40 Commando near sentenced to detention for a "depraved" initiation ceremony where a was forced to drink from a mess tin filled with and vomit from a paddling pool, alongside other humiliations lasting 40 minutes. Senior officers were criticized for failing to intervene in related "" games and assaults during these rituals, with one defendant claiming it was merely "a laugh," though the court viewed it as crossing into criminal territory. These events highlighted ongoing concerns about culture within the unit, leading to military prosecutions but no broader policy overhaul specifically attributed to 40 Commando at the time. In operational training contexts, the 2021 Green Dagger exercise in California's sparked a public dispute when British media reported that 40 Commando had "dominated" a Marine Corps , eliminating nearly all opposition and forcing a surrender midway through, prompting claims of superior tactics and realism in training. Marine Corps officials rebuffed these accounts, stating no surrendered, no near-total elimination occurred, and that 40 Commando participated alongside American forces rather than in direct opposition, emphasizing the exercise's collaborative nature over any humiliating defeat. This exchange underscored tensions in allied training narratives, with UK sources attributing success to innovative " capable" approaches adopted by 40 Commando, while responses prioritized factual correction over competitive framing.

Achievements and Recognitions

Battle Honours and Decorations

40 Commando, as a unit of the Royal Marines, shares the Corps' singular for the in 1704, represented by the globe and laurel device on their and colours; unlike regiments, the Royal Marines do not inscribe multiple campaign honours on their standards but instead designate select operations as "memorable dates" to commemorate significant achievements. One such date for the Corps, involving 40 Commando's leadership, is 20 March 2003, marking the rapid seizure of the in southern during the opening phase of Operation Telic, where the unit advanced under fire to secure oil infrastructure and enable subsequent coalition operations. The unit has received the Firmin Sword of Peace—the highest British military award for exemplary humanitarian and peacekeeping efforts—four times, recognizing contributions beyond combat roles. The inaugural award came in 1966 for stabilizing operations during the and Borneo confrontation, where 40 Commando conducted patrols and civic actions to support local populations against insurgent threats. The most recent, in April 2019, honoured their 2017 deployment to the , delivering aid to over 1,000 hurricane victims in and the after Hurricanes Irma and Maria devastated the region, including engineering repairs to infrastructure and medical evacuations. Individual members have earned gallantry decorations for valour in combat, particularly during the Second World War and . Notable s include:

Strategic Impacts and Legacy

40 Commando's engagements across conflicts have demonstrated the efficacy of commando forces in executing high-risk, rapid-response missions that enable broader strategic objectives, such as securing beachheads and disrupting enemy lines ahead of conventional forces. During Operation Telic in March 2003, the unit conducted amphibious insertions south of Az Zubyir, neutralizing Iraqi defenses and facilitating the advance of coalition ground elements toward , thereby contributing to the swift collapse of regime control in southern . Similarly, in the initial 2001 deployment to , 40 Commando secured on October 7, establishing a critical hub that supported the subsequent influx of international troops and operations against positions. These actions exemplify the unit's role in validating amphibious and expeditionary doctrines emphasizing littoral maneuver and pre-emptive strikes, influencing ' prioritization of versatile, sea-based over static defenses. In post-Cold War scenarios, including the 1982 Falklands campaign, 40 Commando's early helicopter-borne assaults cleared key zones like the Mount Kent area, denying Argentine forces strategic observation posts and aiding the recapture of the islands with minimal initial ground commitments. The legacy of 40 Commando endures in its foundational contributions to commando ethos—adaptability, innovation, and elite proficiency—shaping the Royal Marines' transition to the framework. Formed in 1942 and active in every major British campaign since, the unit has pioneered distributed raiding tactics, as seen in recent restructuring into companies for Littoral Response Groups, which enhance persistent presence in contested maritime domains. This evolution reinforces the strategic imperative of light, technology-integrated forces for crisis intervention and deterrence, with 40 Commando at the of integrating and capabilities to outpace peer adversaries.
