45 Commando
45 Commando Royal Marines is an amphibious commando unit forming part of 3 Commando Brigade Royal Marines, specializing in rapid reaction, expeditionary, arctic, and mountain warfare tasks including vessel protection, domestic resilience operations, and training foreign forces.[1]
Formed in August 1943 from personnel of the disbanded 5th Royal Marines Battalion, the unit landed on Sword Beach during the Normandy invasion on 6 June 1944 as part of the 1st Special Service Brigade.[2][3]
In subsequent decades, 45 Commando contributed to major operations such as Operation Corporate in the Falkland Islands in 1982 and Operation Herrick 5 in Afghanistan in 2006, demonstrating its capabilities in amphibious assaults and counter-insurgency.[1]
Headquartered at RM Condor in Arbroath, Scotland, with over 500 personnel, the unit maintains readiness for global deployments, including recent NATO exercises in Arctic and Baltic environments focused on deterrence and allied interoperability.[1][4][5]
Origins and World War II
Formation as 5th RM Battalion
The 5th Battalion, Royal Marines (5th RM Battalion) was raised on 2 April 1940 at Cowshot Camp in Brookwood, Hampshire, as part of the rapid expansion of Royal Marines forces following the outbreak of the Second World War.[6][7] Commanded by Lieutenant-Colonel H. E. Reading, the battalion drew personnel from existing Royal Marines divisions and new recruits, totaling approximately 800 men organized into rifle companies with supporting elements for amphibious warfare.[8][7] This formation aligned with the British military's need for specialized units capable of independent seaborne operations, reflecting the Admiralty's strategy to bolster naval infantry for raids and landings amid threats from German and Italian forces.[8] Integrated into the 101st Royal Marines Brigade alongside the 1st and 42nd RM Battalions, the 5th RM Battalion was designated for mobile brigade operations under the Royal Marines Division, emphasizing versatility in combined arms tactics with naval support.[6][7] Initial establishment prioritized equipping the unit with Bren light machine guns, Lee-Enfield rifles, and anti-tank weapons, while training commenced immediately on infantry drills and waterborne assault techniques to prepare for expeditionary roles.[8] By late April 1940, the battalion relocated to Hayling Island for specialized boat training, honing skills in landing craft operations essential to its doctrinal purpose.[8][6] A predecessor 5th RM Battalion had existed briefly from September 1918 to February 1919 for coastal defense during the First World War's final months, but the 1940 iteration represented a distinct wartime reconstitution driven by the demands of total mobilization and the evolution toward commando-style raiding forces.[9] The battalion's early composition reflected the Royal Marines' tradition of drawing from naval ratings and volunteers, ensuring a cadre experienced in shipboard duties adapted for land combat projections.[7] This foundational phase laid the groundwork for subsequent amphibious preparations, though the unit's role would later pivot toward commando integration by 1943.[10]Key Operations in Northwest Europe
No. 45 Royal Marine Commando, part of the 1st Special Service Brigade, participated in the Allied invasion of Normandy on 6 June 1944, landing on Queen Red sector of Sword Beach at approximately 0910 hours.[11] Their primary objectives included advancing eastward to secure the left flank of the beachhead, capturing strongpoints at Franceville Plage and Lion-sur-Mer, and linking up with airborne forces holding bridges over the River Orne and Caen Canal.[12] Despite preparatory naval bombardment, the commandos encountered resistance from German anti-tank guns, mortars, and pillboxes, with two landing craft struck during the approach.[12] By evening, they had bypassed the Merville battery—already neutralized by paratroopers—and established defensive positions near Merville, incurring initial casualties including four killed and 14 wounded.[11] On 7 June 1944, elements of 45 RM Commando launched an assault on Franceville Plage, facing intense counterattacks from German forces.[11] The fighting resulted in heavy losses, with one officer and 15 other ranks killed, 38 wounded, and 23 missing; a counterattack by C Troop stabilized the position, earning Major Rushforth the Military Cross.[11] Subsequent days involved holding Merville against probing attacks and evacuating wounded using captured German vehicles.[11] The commando's actions contributed to consolidating the eastern flank of the Sword Beach lodgement amid broader efforts to expand the Normandy bridgehead. Following Normandy, 45 RM Commando, reformed after sustaining approximately 100 casualties in the initial phase, engaged in clearing operations across northern France and Belgium during late 1944.[10] In January 1945, as part of Operation Blackcock, the unit conducted patrols and assaults around the Meuse River near Roermond, Netherlands, targeting German positions on islands like Anchor and Belle Isle amid harsh winter conditions.[13] Fighting patrols encountered violent opposition, securing limited gains but disrupting enemy defenses in the Roer Triangle.[13] The commando played a role in the Rhine crossing during Operation Plunder on 23-24 March 1945, ferrying across the river near Wesel, Germany, under cover of massive artillery support.[14] Advancing eastward, 45 RM Commando assaulted positions to capture the town of Leese after bridging the Weser River, facing fierce resistance in house-to-house fighting.[14] By April 1945, E Troop rested in Drevenack following the Wesel assault, as the brigade pushed toward Bremen, contributing to the final collapse of German forces in northwest Germany.[10] These operations underscored the unit's versatility in amphibious, riverine, and urban combat environments.[14]Post-War Reorganization
Transition to 45 RM Commando
Following the cessation of hostilities in Europe, 45 RM Commando returned to the United Kingdom in June 1945 after a brief posting in occupied Germany.[15] This marked the beginning of its integration into peacetime structures amid broader reforms to British Commando forces, where Army Commando units were disbanded by 1946, transferring the specialized role exclusively to the Royal Marines.[16] In March 1946, as part of this reorganization, 45 RM Commando was redesignated 45 Commando Royal Marines, alongside the restyling of the two other surviving units to form 40 Commando RM and 42 Commando RM.[10][17] These three battalions constituted the nucleus of 3 Commando Brigade Royal Marines, emphasizing amphibious and rapid-reaction capabilities for postwar commitments.[18] The redesignation standardized nomenclature, eliminated wartime designations, and aligned the force with reduced manpower needs while preserving elite training standards developed during the conflict.[19] Prior to completing demobilization processes, the unit deployed to Hong Kong in January 1946 for internal security operations amid regional instability following Japan's surrender, conducting garrison duties until May 1947.[10] This early postwar assignment tested the reorganized Commando's adaptability, involving patrols and counter-insurgency tasks in urban and rural environments, while personnel underwent partial demobilization to peacetime strength levels of approximately 700-800 marines per unit.[15] The transition preserved the unit's operational ethos, with emphasis on rigorous physical conditioning and amphibious expertise, setting the foundation for subsequent Cold War roles.[16]Early Cold War Deployments (1940s-1950s)
Following its redesignation as 45 Commando Royal Marines in March 1946, the unit was deployed to Hong Kong from January 1946 to May 1947 as part of 3 Commando Brigade, conducting internal security duties during the post-war occupation and amid rising communist influence in China.[20] In May 1947, 45 Commando relocated to Malta to form part of Britain's strategic reserve in the Mediterranean, remaining there until December 1948.[19] From this base, the unit dispatched elements to Benghazi, Libya, in March 1948 for garrison duties, and to Haifa, Palestine, in spring 1948, where on 1-2 May it flew in to reinforce 40 Commando, performing policing operations including protection of the Athlit radio station amid escalating Jewish-Arab violence and the impending end of the British Mandate.[19][21] After returning briefly to Hong Kong in December 1948, 45 Commando deployed to Malaya in 1950 as part of 3 Commando Brigade's contribution to the Malayan Emergency, engaging in jungle patrols and counter-insurgency actions against communist terrorists until March 1952, during which the brigade accounted for over 200 insurgents while suffering 34 casualties.[22][23] In September 1955, the Commando was sent to Cyprus to counter the EOKA insurgency seeking union with Greece, undertaking patrols, ambushes, and cordon operations in the Troodos Mountains and other areas, including the Battle of Spilia in 1956 where a detachment clashed with EOKA fighters.[24] During the Suez Crisis, 45 Commando participated in Operation Musketeer, conducting the world's first combat helicopter assault on 5-6 November 1956; embarked on HMS Theseus, approximately 450 marines were inserted via 22 Westland Whirlwind helicopters into Port Said, securing key objectives including bridges and the Raswa oil refinery within 90 minutes despite light resistance.[25][26][27]Decolonization and Counter-Insurgency Era
Operations in the Middle East and Asia (1950s-1960s)
In the early 1950s, 45 Commando deployed to Malaya as part of the British response to the Malayan Emergency, arriving from Hong Kong in June 1950 to conduct counter-insurgency operations against communist guerrillas. The unit participated in jungle patrols, ambushes, and village securing missions alongside other elements of 3 Commando Brigade, contributing to the broader effort that accounted for over 200 enemy casualties by the brigade while suffering 34 total casualties from May 1950 to March 1952.[23] These operations emphasized rapid mobility and small-unit tactics in dense terrain, with 45 Commando returning to Hong Kong by December 1948 prior to this deployment and withdrawing from active combat roles in Malaya by 1952.[28] During the Suez Crisis, 45 Commando executed the world's first combat helicopter assault on 5 November 1956, landing approximately 450 marines and their equipment at Port Said, Egypt, from HMS Theseus using 22 Westland Whirlwind helicopters in under 90 minutes.[25] This amphibious-airborne operation, part of Operation Musketeer, secured key objectives including bridges and the Gamil airfield amid Anglo-French efforts to seize the Suez Canal following its nationalization by Egypt.[26] The assault demonstrated emerging helicopter tactics for rapid insertion but faced logistical challenges from limited lift capacity and enemy resistance, with the commandos linking up with paratroopers and advancing inland before a ceasefire halted further gains on 6 November.[29] From March 1960, with an advance party arriving on 10 March, 45 Commando maintained a prolonged presence in Aden Protectorate until November 1967, engaging in counter-insurgency against nationalist rebels during the Aden Emergency.[30] Key actions included operations in the Radfan mountains starting in April 1964, where the unit supported Federal Regular Army forces in clearing dissident strongholds like the Dhanaba Basin through combined infantry assaults and helicopter insertions alongside 3 PARA.[31] In January 1964, during a brief diversion from Aden duties, elements deployed to Tanganyika to suppress an army mutiny, restoring order through show-of-force patrols before returning to focus on Aden's urban and rural threats, including sniper engagements in Crater district.[32] These missions highlighted the commandos' adaptability to arid environments and irregular warfare, though the withdrawal in 1967 marked the end of British colonial commitments amid escalating violence.[30]Aden Withdrawal and Reorientation (1960s-1970s)
45 Commando arrived in Aden on 23 April 1960 as part of the British response to escalating unrest in the protectorate, conducting multiple counter-insurgency operations against dissident groups supported from Yemen, particularly in the Radfan mountains north of the city.[30] The unit's efforts focused on securing key routes like the Dhala Road, employing night assaults, helicopter insertions, and combined arms tactics with artillery and air support to disrupt rebel supply lines and strongholds.[30] Notable actions included supporting Federal Regular Army advances on Bakri Ridge in January 1964 and raids such as the May 1964 assault on Wadi Dhubsan, where X Company encountered heavy resistance, resulting in two marines killed—including Marine David Wilson—and one marine suffering a leg amputation from enemy fire.[30] As the Aden Emergency intensified with attacks by the National Liberation Front (NLF) and others, 45 Commando maintained security duties amid rising casualties and political pressure for withdrawal, which British policy accelerated following the 1966 decision to grant independence to South Arabia.[33] By September 1967, with families evacuated, the unit relocated from its Little Aden base to urban flats in preparation for departure.[33] Serving as the penultimate major garrison element, 45 Commando was relieved by 42 Commando on 28 November 1967; the final withdrawal occurred the next day, with personnel airlifted from Khormaksar Airfield starting shortly before midnight on 28 November and concluding at 1:30 p.m. on 29 November via RAF aircraft and helicopters from HMS Albion.[33] On the last day, the unit's Recce Troop placed the Union Flag and White Ensign on Jabal Shamsan overlooking the harbor, symbolizing the end of 128 years of British presence.[33] The withdrawal marked 45 Commando's return to the United Kingdom after 24 years of continuous overseas deployments since World War II, initially basing at Plymouth before transferring to Arbroath, Scotland, in 1971 to leverage northern terrain for specialized training.[1] In the 1970s, amid Britain's strategic pivot to NATO's northern flank amid Cold War tensions, the unit reoriented from desert counter-insurgency to arctic and mountain warfare, conducting rigorous exercises in Scotland's Cairngorms and Norway to develop capabilities for high-altitude, sub-zero operations, including survival, mobility, and tactical maneuvers in extreme cold.[34][35] This shift emphasized amphibious reinforcement roles against potential Soviet threats in Scandinavia, integrating cold-weather equipment and doctrines honed through annual winter deployments.[34]Falklands War and Late Cold War
Operation Corporate (1982)
45 Commando, assigned to 3 Commando Brigade Royal Marines, deployed as part of the British response to the Argentine invasion of the Falkland Islands on 2 April 1982. The brigade, including 45 Commando, landed at San Carlos Water and Ajax Bay on East Falkland starting 21 May 1982, establishing a bridgehead amid Argentine air attacks.[36] Several members of the unit were killed or wounded in a bombing raid on Ajax Bay field hospital and supply areas on 27 May 1982, with at least five fatalities recorded from the attack or subsequent wounds.[37] From the landing site, 45 Commando executed a 56-mile yomp across rugged peat moorland, hills, and streams toward Port Stanley, burdened with heavy equipment including artillery support. The march, conducted in cold, wet conditions and under threat of mines and patrols, relied partly on foot after the loss of helicopters aboard the sunk SS Atlantic Conveyor on 28 May 1982, forcing many to complete the trek on foot.[36] The advance included staging at positions such as Douglas Settlement and Teal Inlet before positioning for assaults on the outer Argentine defensive ring around the capital. On the night of 11–12 June 1982, 45 Commando launched a night assault on the Two Sisters ridge, a dominant feature south of Port Stanley held by Argentine infantry and artillery observers. The operation involved close-quarters fighting in darkness, with the commandos securing the position after overcoming resistance, contributing to the breach of Argentine lines. Three marines died during direct action on the ridge, while four others from the unit were killed hours earlier in a friendly fire incident when a patrol was mistaken for Argentine forces by British artillery.[38][37] By 14 June 1982, as Argentine commander Mario Benjamín Menéndez surrendered to British forces, 45 Commando had advanced to Sapper Hill, within a mile of Port Stanley, halting short due to minefields. The unit then entered the capital and assisted in disarming and processing over 11,000 Argentine prisoners. In total, 12 members of 45 Commando were killed during Operation Corporate, reflecting losses from air attacks, ground combat, and the pre-assault friendly fire.[38][37]Arctic Training and NATO Commitments (1970s-1980s)
In early 1970, 45 Commando initiated specialized Arctic training in northern Norway, marking its establishment as Britain's first dedicated mountain and Arctic warfare unit. Personnel tested new equipment, including medical gear, under sub-zero conditions during February exercises focused on survival and mobility in extreme cold.[39] The following winter, in February 1971, approximately 500 marines from 45 Commando, supported by 145 (Maiwand) Battery of 29 Commando Regiment Royal Artillery, conducted intensive snow commando training in northern Norway. This deployment emphasized ski operations, tracked vehicle maneuvers, and adaptation to Arctic terrain, laying the foundation for annual winter rotations.[40] These efforts fulfilled the unit's role within 3 Commando Brigade's NATO commitments, preparing for rapid reinforcement of Norway's northern flank against potential Warsaw Pact incursions during the Cold War. By specializing in cold weather warfare from the 1970s onward, 45 Commando conducted yearly three-month deployments to Norway, honing amphibious assaults, patrols, and defensive tactics in fjords and tundra environments.[41] Throughout the 1970s and 1980s, such training ensured readiness for NATO's Allied Forces Northern Europe (AFNORTH), where UK forces were pledged to counter Soviet naval and ground threats via the Barents Sea and Norwegian coast. The unit's expertise in sub-zero operations, including equipment trials like ski-trics for enhanced mobility, directly supported deterrence strategies amid escalating tensions.[42]Post-Cold War Operations
Gulf War and Humanitarian Missions (1990s)
In April 1991, following the conclusion of the Gulf War, 45 Commando deployed to northern Iraq as part of Operation Haven, a multinational humanitarian effort to protect and assist Kurdish refugees fleeing Saddam Hussein's forces. The unit, integrated into 3 Commando Brigade alongside 40 Commando and Dutch marines, established secure zones in the Zakho region, providing aid, medical support, and security against potential reprisals while coordinating with coalition forces to distribute food, water, and shelter to over 500,000 displaced civilians. Operations lasted approximately two months, with 45 Commando withdrawing by late June after stabilizing the area and enabling refugee returns.[43] In October 1994, amid heightened tensions from Iraqi troop movements near the Kuwaiti border, 45 Commando was airlifted to Kuwait under Operation Vigilant Warrior to reinforce coalition defenses and deter further aggression. Elements of the unit operated alongside the U.S. 24th Infantry Division's 1st Brigade, conducting patrols, establishing checkpoints, and preparing defensive positions along the border, contributing to the rapid de-escalation as Iraq withdrew its forces under international pressure. The deployment underscored the unit's role in rapid reaction contingencies in the Gulf region post-1991 war.[44] In November 1998, 45 Commando was redirected from exercises in Belize to support Operation Tellar, delivering humanitarian relief in Honduras and Nicaragua after Hurricane Mitch devastated the region, causing over 11,000 deaths and widespread flooding. Over 1,000 marines from the unit, embarked on HMS Ocean and support vessels like RFA Sir Tristram, conducted amphibious landings to distribute aid, perform search-and-rescue operations for stranded villagers, and clear debris in flooded areas such as the Rio Coco valley, where river levels rose more than 50 feet; efforts focused on self-defense-armed patrols to secure relief convoys amid limited infrastructure. The mission highlighted the unit's amphibious capabilities in disaster response, aiding recovery in isolated communities before redeployment.[45][46]Iraq and Afghanistan Deployments (2000s)
In 2003, 45 Commando deployed to Iraq as part of Operation Telic 1, contributing to the initial coalition invasion and subsequent stabilization efforts.[47] The unit participated in ground operations amid the broader campaign to remove Saddam Hussein's regime, focusing on securing key areas and supporting multinational forces.[47] Earlier, in April 2002, 45 Commando Group deployed to Afghanistan for Operation Jacana, a series of raids and clearance operations in eastern provinces such as Khost and Paktia to deny sanctuary to al-Qaeda and Taliban remnants.[1] Working alongside U.S. forces and Australian SAS, the commandos conducted Operation Ptarmigan to clear high mountain valleys and Operation Condor to flush out insurgents, culminating in the operation's end on 9 July 2002 after neutralizing several enemy positions.[1][48] From May to October 2006, elements of 45 Commando served in Operation Herrick 5, undertaking roles including Operational Mentoring and Liaison Teams (OMLT) to train Afghan National Army units and supporting Battlegroup North East in northern Helmand Province against Taliban insurgents.[1] During Herrick 6 (October 2006–April 2007), companies from 45 Commando, such as W Company, operated in Sangin, conducting patrols and engagements that resulted in casualties including Lance Corporal Mathew Ford on 15 January 2007.[49] In Operation Herrick 9 (November 2008–April 2009), 45 Commando's Whiskey and X-ray Companies held positions in Sangin, Helmand Province, executing raids like Operation Diesel on 7 December 2008, where over 700 troops, including 45 Commando elements, targeted Taliban strongholds in Garmsir, killing over 20 insurgents.[50] The deployment saw intense fighting, with losses such as Marine Alexander Lucas on 24 November 2008 and Marine Darren Smith on 15 February 2009 during patrols from Forward Operating Base Nolay.[51][50] These operations emphasized close-quarters combat and mentoring to counter insurgency threats.[1]Recent Engagements and Future Commando Force (2010s-2020s)
In the early 2010s, 45 Commando maintained operational tempo in Helmand Province, Afghanistan, where Zulu Company partnered with Afghan National Army units to conduct clearance operations aimed at neutralizing insurgent threats to British forces and local populations.[52] A notable example was Operation TOR KANJAK (Black Thorn) in July 2011, involving joint patrols and strikes to dominate high-risk areas.[52] These efforts contributed to transitional security handovers amid the broader International Security Assistance Force drawdown, with the unit's final major combat rotations concluding by 2014 as UK commitments shifted from sustained ground presence to advisory roles.[53] Post-Afghanistan, 45 Commando pivoted to high-readiness training and NATO interoperability, emphasizing amphibious assault, arctic warfare, and crisis response. In 2022, the unit led beachhead establishment and raiding operations during Exercise Green Dagger in the Eastern Mediterranean, launching from RFA Lyme Bay and HMS Albion with Merlin helicopters to simulate contested littoral maneuvers.[54] Later that year, elements supported European deployments, including amphibious integration with British Army units in Norway and Turkey as part of NATO's Land Forces exercises.[55] In 2023, personnel from 45 Commando conducted joint training with US Army 10th Special Forces Group in Grafenwöhr, Germany, focusing on reconnaissance and special operations tactics.[56] Reports from former Royal Marines leadership indicate discreet high-risk missions in Ukraine that year, including rapid evacuation support redirected from Norwegian winter exercises, though official Ministry of Defence confirmation remains limited to broader European readiness contributions.[57] By the mid-2020s, engagements centered on specialized environmental training to sustain core competencies. In August 2025, Marines from 45 Commando completed Exercise Green in California's Pickel Meadows, honing mountain warfare skills with live-fire assaults and survival drills at altitudes exceeding 6,000 feet.[58] Concurrently, night raids on Norway's Senja Island from RFA Lyme Bay tested cold-weather amphibious insertion against simulated peer adversaries.[59] These activities underscore the unit's role within Littoral Response Group (North), maintaining surge capacity for Indo-Pacific contingencies or European deterrence. The Future Commando Force (FCF) initiative, launched in the late 2010s, restructures 45 Commando from traditional battalion formations into modular, technology-integrated teams optimized for distributed lethality and persistent campaigning.[60] This evolution reduces force density—targeting operations with units as small as platoon-sized strike teams—while enhancing sensors, unmanned systems, and precision fires for raiding, reconnaissance, and disruption in contested maritime environments.[61] As the primary arctic and mountain specialists within UK Commando Force, 45 Commando retains Norway-based prepositioning for rapid reinforcement of NATO's northern flank, but FCF emphasizes multi-domain integration with allies like US Marine Corps and Special Operations Command, enabling scalable responses to hybrid threats over large theaters.[62] Implementation, backed by £1.3 billion in investments through 2030, prioritizes agility over mass, with 45 Commando forming the second-line maneuver element alongside 40 Commando in high-readiness cycles.[56]Role and Capabilities
Amphibious and Special Operations Doctrine
45 Commando, as a core component of the Royal Marines' 3 Commando Brigade, adheres to amphibious doctrine emphasizing rapid ship-to-objective maneuver warfare, enabling deployment from maritime platforms to seize key terrain or objectives ashore with minimal reliance on fixed bases.[1] This approach prioritizes surprise, mobility, and exploitation of enemy vulnerabilities through integrated surface and air insertion methods, including landing craft, helicopters, and specialized raiding vessels like the Commando Raiding Craft, which facilitate high-speed, low-observable approaches in contested littoral environments.[63] Historical precedents, such as the unit's participation in the Normandy landings on Sword Beach on 6 June 1944, underscore the doctrine's focus on establishing beachheads under fire to support follow-on forces.[2] In special operations contexts, 45 Commando employs small, self-sufficient teams for reconnaissance, raiding, and crisis response, operating at extended ranges from command and control to gather intelligence, disrupt enemy logistics, or conduct direct action strikes.[62] These capabilities align with commando-level tasks, distinct from Tier 1 special forces but enhanced by specialized equipment for littoral strike and persistent surveillance, as demonstrated in exercises involving night-time raids from amphibious ships like RFA Lyme Bay during NATO operations in Norway in March 2025.[4] The unit's doctrine stresses decentralized decision-making and adaptability, with recent acquisitions such as snowmobiles augmenting mobility for reconnaissance and raiding in extreme terrains.[64] Under the Future Commando Force transformation initiated in the late 2010s, 45 Commando's doctrine has evolved toward a special operations-capable amphibious advanced force, supporting NATO Level 2 operations through distributed, forward-deployed Littoral Response Groups focused on deterrence, persistent engagement, and precision strikes in contested maritime domains.[65] This shift integrates unmanned systems, long-range sensors, and SOF-specific gear to enable scalable responses from raid-scale actions to brigade-level maneuvers, countering anti-access/area-denial threats while maintaining the Royal Marines' expeditionary ethos.[62] Training regimens, including the Amphibious Warfare Course, ensure proficiency in joint planning from operational directives to execution, fostering interoperability with naval and allied forces.[66]Arctic and Mountain Warfare Specialization
45 Commando functions as the United Kingdom's designated specialists in cold weather warfare, emphasizing arctic and mountain operations within the Royal Marines structure.[1] This role leverages the unit's basing at RM Condor in Arbroath, Scotland, facilitating rapid deployment to northern environments.[1] The specialization encompasses survival techniques, mobility across snow and ice, and tactical maneuvers in sub-zero conditions, integrated into broader amphibious and expeditionary doctrines.[67] Arctic training predominantly occurs in Norway, where 45 Commando participates in annual exercises such as Operation Clockwork to maintain NATO interoperability.[68] In February 2025, unit personnel endured temperatures as low as -20°C during patrols and raids on Senja Island, simulating high-threat scenarios from amphibious platforms like RFA Lyme Bay.[4] The foundational Cold Weather Warfare Course, conducted at Camp Viking since the 1970s, structures instruction into survival (e.g., shelter-building and foraging), mobility (skiing and snowshoe navigation), and warfare phases (live-fire assaults and demolitions).[67] This program builds on Royal Marines' cold weather expertise established in the 1940s, with the UK sustaining over 50 years of Norwegian training to ensure operational readiness in polar regions.[69] Mountain warfare capabilities complement arctic focus through specialized cadre training, including joint operations with allied forces. In 2025, elements of 45 Commando trained at the US Marine Corps Mountain Warfare Training Center in California's Sierra Nevada, at elevations exceeding 7,000 feet, testing gear like insulated clothing and avalanche mitigation in rugged terrain.[70] These sessions emphasized high-altitude assaults, comparing equipment such as cold-weather boots and weapons systems with US counterparts to refine interoperability.[71] Advanced demolitions and close air support integration, as demonstrated in 2020 Norwegian exercises with 29 Commando Regiment, further enhance sabotage and strike capabilities in extreme environments.[72][73] The unit's proficiency supports NATO's northern flank deterrence, with rotations ensuring collective proficiency in sub-arctic logistics, such as helicopter operations in whiteout conditions.[4] This specialization remains critical amid heightened geopolitical tensions, prioritizing empirical adaptation to causal factors like prolonged darkness and hypothermia risks over doctrinal assumptions.[69]Organization and Training
Unit Structure and Subunits
45 Commando Royal Marines is structured as a battalion-sized formation within 3 Commando Brigade, comprising approximately 650 personnel organized into six companies to enable rapid deployment for amphibious, raiding, and arctic operations.[1] The unit includes a Command Company for headquarters and administrative functions, a Logistics Company for sustainment, and four maneuver companies—Whiskey (W Company), X-Ray (X Company), Yankee (Y Company), and Zulu (Z Company)—each typically consisting of three rifle troops and a support troop equipped for close combat, stand-off engagements, and specialized environments.[74] Command Company encompasses the regimental headquarters, signals troop, medical section, quartermaster's department, and physical training elements, ensuring operational command, communications, health services, and logistical oversight. Logistics Company delivers combat service support, including vehicle maintenance, supply distribution, catering, and ammunition handling to sustain prolonged field operations. Among the maneuver companies, Whiskey Company focuses on close-quarters and urban combat tactics, while X-Ray and Zulu Companies emphasize stand-off battles with heavier weapons for fire support and anti-armor roles; Yankee Company receives dedicated training for mountain and arctic warfare, reflecting 45 Commando's specialization in cold-weather environments.[74][1] Subunits are designed for flexibility, with troops capable of task-organized groupings for reconnaissance, direct action, or support roles under the UK's Commando Force framework, which integrates Royal Marines with joint assets for high-readiness missions. This structure evolved from post-World War II reorganizations, standardizing companies from earlier troop-based formations by the 1960s to enhance scalability in NATO and expeditionary contexts.[44][75]Selection, Training, and Readiness
Personnel of 45 Commando must qualify as Royal Marines Commandos via the standardized selection and initial training at the Commando Training Centre Royal Marines (CTCRM) in Lympstone, Devon, before assignment to the unit.[76][1] Selection commences with an online application, followed by the Defence Aptitude Assessment testing verbal, numerical, spatial, and mechanical reasoning.[76] Candidates then face a formal interview, Pre-Joining Fitness Assessment, and the 4-day Royal Marine Candidate Preparation Course evaluating fitness, swimming, and medical fitness.[76] Successful recruits complete 32 weeks of training in four phases: individual skills (weeks 1-10), team and section skills (weeks 11-15), troop and urban skills with test exercise (weeks 16-23), and Commando phase (weeks 24-32), culminating in qualification to wear the green beret.[76] Post-qualification postings to 45 Commando, based at RM Condor in Scotland with over 500 personnel, emphasize specialist preparation in arctic, mountain, amphibious, and expeditionary warfare.[1] Unit training incorporates annual arctic exercises in Norway, including reconnaissance patrols and raids during NATO operations such as those concluding in March 2025.[4][67] Mountain warfare proficiency is maintained through deployments like the August 2025 exercise at Pickel Meadows, California, involving 120 marines testing equipment and tactics in extreme terrain.[58] Readiness is sustained via rotational high-alert status within the UK Commando Force, enabling short-notice deployments for rapid reaction, humanitarian aid, or vessel protection worldwide.[1]Equipment and Logistics
Weapons and Vehicles
45 Commando, as part of the Royal Marines, is equipped with standard infantry weapons suited for amphibious, arctic, and high-mobility operations, including the SA80A2 5.56mm assault rifle as the primary individual firearm, capable of sustained fire in diverse environments.[77] Support weaponry encompasses the L7A2 7.62mm general purpose machine gun for suppressive fire and the 81mm mortar for indirect bombardment up to 5,650 meters, delivering high-explosive, smoke, or illumination rounds via a two-person crew.[77] Sniper capabilities are provided by the L96 .338 caliber rifle, effective beyond 1 kilometer with adjustable features for precision in cold or rugged terrain.[77] Anti-structure and anti-armor threats are addressed with man-portable systems such as the Javelin guided missile, which defeats armored vehicles and low-flying helicopters using day/night sights, and the Next Generation Light Anti-Tank Weapon (NLAW), offering predicted line-of-sight engagement up to 1 kilometer by a single operator.[77] Pistols like the 9mm L131A1 supplement close-quarters needs, while under-slung grenade launchers on the SA80 enable enhanced lethality against personnel and light cover.[77] Vehicles emphasize mobility across extreme terrains, with the Viking (BvS10) armoured all-terrain vehicle forming a core asset for 45 Commando; this articulated, amphibious platform transports troops and equipment over snow, ice, and water, supporting arctic deployments in Norway.[78] [79] Complementing this are BV206 tracked carriers for oversnow logistics and lightweight all-terrain vehicles like quad bikes and Polaris MRZR for rapid reconnaissance.[78] Recent investments include £10 million in advanced snowmobiles to replace older BV206 and Viking units, enhancing raiding and patrol speeds in sub-zero conditions as part of Future Commando Force adaptations.[80] In theatre-specific roles, such as Afghanistan patrols, Jackal 2 high-mobility vehicles provided protected firepower, though arctic specialization prioritizes tracked and amphibious types.[78]Adaptations for Modern Operations
To address the challenges of asymmetric warfare in environments like Afghanistan, 45 Commando adopted the Viking BvS 10 all-terrain tracked vehicle, which provided protected mobility across desert and mountainous terrain during operations in Helmand Province starting in 2006.[81] This articulated, amphibious platform, consisting of two linked tracked units, enabled rapid advances and casualty evacuation under fire, with upgrades including mine blast protection to counter improvised explosive devices prevalent in counter-insurgency settings.[82] The vehicle's versatility supported transitions from arctic specialization to expeditionary roles, maintaining operational tempo in austere conditions without reliance on extensive road networks.[83] Logistical adaptations emphasized self-sufficiency, with the unit sustaining 30-40 days of supplies during patrols in Nad 'Ali South in 2011, contrasting with insurgent hand-to-mouth operations and enabling prolonged engagements.[52] Integration of quad bikes facilitated quick repositioning of mortars and crews, enhancing fire support in fluid battlespaces.[78] As part of the Future Commando Force transformation in the 2020s, 45 Commando shifted to lighter logistics footprints, incorporating drones for resupply—such as heavy-lift models demonstrated in trials—and autonomous systems to reduce manpower demands in high-threat littoral environments.[61] Weaponry evolutions focused on precision and anti-armor capabilities suited to peer and hybrid threats. Retained core systems like the 81mm mortar for indirect fire up to 5,650 meters and Javelin missiles for engaging armored vehicles, while testing next-generation light anti-tank weapons (NLAW) for close-range, top-attack profiles against modern tanks.[77] Refurbishment of existing all-terrain vehicles in 2024 preceded acquisition of future models, ensuring compatibility with rapid global deployment via Littoral Response Groups.[84] These changes prioritize agility, technological integration, and reduced logistical tails for sustained operations in contested domains.[61]Leadership and Honours
