40 Commando
40 Commando Royal Marines is a battalion-sized light infantry formation within the United Kingdom's Royal Marines, specializing in amphibious warfare, rapid reaction deployments, and operations across extreme environments including Arctic, mountain, and expeditionary settings.[1]
Formed on 14 February 1942 as part of the wartime expansion of British commando forces, the unit participated in key Second World War operations such as the Dieppe Raid, landings in Italy, and campaigns in the Aegean islands, establishing its reputation for raiding and reconnaissance in hostile terrain.[2] Post-war, 40 Commando engaged in counter-insurgency in Malaya, secured refugee zones in northern Iraq in 1991, and contributed to operations in Northern Ireland and Norway.[2] [1]
In recent decades, the unit has undertaken high-intensity missions, including securing Bagram Airfield as the first British force in Afghanistan in 2001 and leading the amphibious assault on the Al Faw Peninsula during the 2003 Iraq invasion, which denied Saddam Hussein's regime control over vital oil infrastructure and earned official recognition as one of the Royal Marines' finest operational achievements.[3] [4] [5] Based at Norton Manor Camp near Taunton, Somerset, 40 Commando continues to train for global threats under the evolving Future Commando Force structure, emphasizing innovation in sea-raiding and advanced technologies.[1]
Overview and Role
Formation and Mandate
40 Commando Royal Marines was established on 14 February 1942 at Deal, Kent, initially designated as the Royal Marine Commando and comprising volunteers from existing Royal Marines units organized into A, B, and X companies.[2] This formation marked the creation of the first dedicated Royal Marines commando unit, intended to conduct raiding and reconnaissance operations in support of Allied amphibious efforts during World War II.[6] The unit was briefly redesignated as Royal Marine Commando (A) before adopting the numerical title No. 40 Royal Marine Commando on 12 October 1942.[7] Following its initial deployment, 40 Commando participated in the Dieppe Raid on 19 August 1942, suffering heavy casualties but gaining valuable experience in combined operations.[1] The unit was disbanded in October 1945 after service in Italy and other theaters but was reformed on 16 March 1947 in Hong Kong as part of 3 Commando Brigade to maintain the Royal Marines' commando capability amid post-war commitments in Asia.[8] The mandate of 40 Commando centers on serving as a light infantry battalion within the UK's Commando Force, specializing in rapid reaction forces for amphibious, Arctic, mountain, and expeditionary warfare.[1] It maintains readiness for global deployment at short notice to execute sea-based raiding, reconnaissance, and crisis response missions, while also supporting humanitarian aid and disaster relief operations in extreme environments.[1] This role emphasizes high mobility, adaptability, and integration with naval assets to address diverse threats from littoral zones to inland objectives.[1]Current Organization and Structure
40 Commando Royal Marines operates as a battalion-sized formation within the United Kingdom Commando Force, comprising approximately 500 personnel held at high readiness for global crisis response and expeditionary operations.[9] Under the Future Commando Force 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.[10] 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 United States Marine Corps.[10][11] The strike companies are supported by specialized enablers, including logistics, information warfare, and base support functions, allowing sustained operations without reliance on fixed infrastructure.[9] 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 Indo-Pacific theaters.[10][12] 40 Commando's companies emphasize adaptability to extreme environments, with a doctrinal focus on jungle and desert warfare to complement broader Commando Force capabilities.[13] Headquartered at Norton Manor Camp in Taunton, Somerset, the unit maintains a command company for leadership, planning, and coordination, ensuring rapid force generation for tasks ranging from humanitarian assistance to high-intensity combat.[1] As of 2025, this organization reflects ongoing adaptations to peer adversary threats, emphasizing distributed lethality and reduced logistical footprints over traditional battalion maneuvers.[10][13]Capabilities and Equipment
Training and Specialization
Personnel assigned to 40 Commando complete the Royal Marines' 32-week Commando Course at the Commando Training Centre Royal Marines (CTCRM) in Lympstone, Devon, 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.[14] This program, the longest infantry basic training among NATO forces, emphasizes physical endurance, weapons handling, fieldcraft, and amphibious tactics to forge versatile commandos capable of independent action.[14] Post-initial training, 40 Commando Marines specialize in littoral maneuver and expeditionary warfare within the UK Commando Force framework, focusing on rapid deployment for raiding, amphibious assaults, and operations in austere environments.[1] Unit training includes scenario-based exercises simulating peer-adversary threats, such as deep reconnaissance and strike missions in contested spaces, often integrated with joint forces.[15] Specializations encompass jungle warfare, desert operations, arctic survival, and urban combat, with Marines qualifying in skills like combat assault breaching and information warfare support.[16] Recent exercises highlight this adaptability: in May 2023, approximately 140 troops from Charlie Company conducted jungle patrolling, navigation, break-contact drills, and ambushes in Brunei to prepare for Indo-Pacific contingencies.[17] Similarly, in December 2020, Charlie Company teams trained in the Mojave Desert on maneuver under fire and battlespace integration, while January 2023 Hawaii drills refined ambush tactics in dense terrain.[15][18] These rotations ensure proficiency across terrains, enabling 40 Commando to deploy globally at short notice against diverse threats.[1]Weapons and Support Systems
The primary individual weapon for marines in 40 Commando is the L403A1 (KS-1) carbine, a 5.56mm selective-fire rifle adopted in 2023 as the Alternative Individual Weapon to supplement or replace older SA80 variants in Commando Force units, including 40 and 45 Commando, with over 1,000 units delivered for enhanced close-quarters and maneuverability in littoral environments.[19][20] Complementing this, some elements have transitioned to the SIG Sauer MCX (L403A1 AWS variant) as a primary close-combat rifle, emphasizing modularity and suppressibility for special operations tasks.[21] For precision engagements, designated marksmen employ the L129A1 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 L96A1 in .338 Lapua Magnum for targets exceeding 1 km with adjustable stocks and bipods.[22] Support weapons include the L110A2 light machine gun (5.56mm) for squad automatic fire and the L7A2 general-purpose machine gun (7.62mm) for sustained suppression, alongside the L134A1 Heavy Machine Gun (.50 BMG) for vehicle-mounted or anti-materiel roles.[23] Heavy support systems encompass indirect fire from 81mm mortars, operated by two-man teams delivering high-explosive, smoke, or illumination rounds up to 5,650 meters, as demonstrated by 40 Commando's mortar platoons in recent exercises like PREDATORS RUN.[22][24] Anti-armor capabilities are provided by the Next Generation Light Anti-Structure Weapon (NLAW), a man-portable 150mm rocket with 1 km range and predictive fire-and-forget guidance for defeating light vehicles and bunkers, and the Javelin missile system, a medium-range fire-and-forget anti-tank guided weapon transportable by one marine, capable of top-attack profiles against armored threats including tanks and low-flying helicopters.[22] Each commando unit, including 40 Commando, maintains an Anti-Tank Troop with at least six Javelin teams for integrated platoon-level support.[25] Grenade launchers such as the L17A2 (40mm underslung) augment small-arms fire for area suppression and anti-personnel effects.[22]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 Dieppe Raid (Operation Jubilee) on 19 August 1942.[1] The unit, comprising approximately 370 men under Lieutenant Colonel Joseph Picton Phillips, was tasked with landing east of the port to neutralize coastal batteries and secure the harbor area for follow-on forces.[26] Facing intense German defenses, including machine-gun fire and artillery from elevated positions, the commandos encountered immediate setbacks with landing craft under heavy suppression; many were killed or captured during the assault, and the objective was not achieved.[27] Phillips was killed in action, and the raid resulted in near-total losses for the commando element, highlighting deficiencies in amphibious tactics that informed later Allied planning.[28] In the Italian Campaign, 40 Commando participated in Operation Devon, an amphibious landing at Termoli on the Adriatic coast on 3 October 1943, alongside No. 3 Commando and elements of the Special Raiding Squadron.[29] 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.[30] By dawn, Termoli 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.[31] The operation succeeded in outflanking the German Gustav Line defenses, though 40 Commando suffered casualties from the ensuing fighting. The unit continued operations in Italy, engaging on the Garigliano River front in January 1944 before reinforcing the Anzio beachhead (Operation Shingle) by late February.[31] At Anzio, 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.[32] 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.[33] Throughout 1943–1945, 40 Commando supported Adriatic operations, including raids and landings along the Dalmatian coast and in Yugoslavia to harass Axis garrisons and support partisan forces, as part of broader efforts to tie down German reserves.[1] In the Spring 1945 offensive, the unit executed a feint during Operation Roast 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.[34] Supported by Italian partisans, this maneuver involved amphibious elements navigating shallow lagoons and canals against fortified positions, facilitating the advance into the Po Valley and hastening the Italian theater's conclusion, with 40 Commando sustaining further casualties in close-quarters combat.[35]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.[36][37] During the Cyprus Emergency (1955–1959), 40 Commando, based in Malta, deployed to the island to counter EOKA terrorist activities seeking enosis with Greece; from February 1957 to July 1958, the unit conducted patrols and cordon operations amid ethnic tensions between Greek and Turkish Cypriots.[7][31] In the Indonesia–Malaysia Confrontation (1963–1966), 40 Commando undertook six tours in Borneo, including operations in Sabah 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.[38][39] For the Aden Emergency (1963–1967), 40 Commando operated in the Federation of South Arabia, particularly in the Dhala region in 1963, providing support to the Federal National Guard against dissident tribesmen and nationalist insurgents through patrols and fortified positions to maintain order ahead of British withdrawal.[40][31]
Cold War Conflicts
In November 1956, during Operation Musketeer—the Anglo-French-Israeli intervention in the Suez Crisis—40 Commando conducted amphibious landings at Port Said, Egypt, alongside 42 Commando, to seize control of the Suez Canal Zone following its nationalization by President Gamal Abdel Nasser.[41] On 6 November, supported by Centurion 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.[42] The operation faced logistical challenges, including limited air support due to political constraints from the United States and Soviet Union, 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.[43] The unit's most prominent Cold War combat deployment occurred during the Falklands War in 1982, as part of 3 Commando Brigade in Operation Corporate, the British response to Argentina's invasion of the Falkland Islands on 2 April.[1] 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.[1] 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.[44] 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.[45] Beyond these engagements, 40 Commando conducted operations to safeguard British interests in volatile regions, such as a 1964 deployment to the Congo during the Congo Crisis, where the unit evacuated civilians and protected assets amid proxy conflicts between Cold War superpowers.[36] These missions underscored the commando's amphibious expertise in rapid response scenarios, though they involved limited direct combat compared to Suez and the Falklands.[1]Post-Cold War Deployments
In 1991, 40 Commando deployed to northern Iraq as part of Operation Provide Comfort to secure the safety of Kurdish refugees fleeing persecution by Saddam Hussein's forces and to support regional stabilization efforts.[1] The unit conducted patrols and established secure zones amid harsh mountainous terrain, contributing to the establishment of a safe haven until July 1991.[46] Following this, 40 Commando undertook multiple tours in Northern Ireland during the Troubles' later phases, focusing on counter-terrorism operations, riot control, and community policing in volatile areas.[1] These deployments, spanning the 1990s, involved four rotations emphasizing intelligence-led patrolling and vehicle checkpoints to disrupt paramilitary activities.[1] The unit participated in the 2001 invasion of Afghanistan, becoming the first British ground force to deploy, securing Bagram Airfield near Kabul on 13 November and subsequently conducting urban patrols in the capital to counter Taliban remnants.[3] Elements integrated with special forces for mountain operations targeting al-Qaeda positions.[47] During Operation Telic in 2003, 40 Commando executed an amphibious helicopter assault on the Al Faw Peninsula on 20 March, landing via Sea King helicopters as the initial conventional coalition troops in Iraq.[1] The operation secured vital oil infrastructure, preventing sabotage, and cleared Iraqi coastal defenses amid chemical threat risks, advancing inland to link with ground forces.[48][5] 40 Commando returned to Afghanistan multiple times, including a 2007 deployment under 52 Infantry Brigade in Helmand Province for counter-insurgency patrols and base security.[49] In April 2010, as part of Operation Herrick 12, the unit operated in Sangin district, engaging in intense close-quarters combat against Taliban forces, mentoring Afghan troops, and dismantling improvised explosive devices until October.[50] These efforts supported provincial reconstruction amid high casualty rates from ambushes and booby traps.[50] The unit also contributed to special forces support groups in Afghanistan, providing firepower and logistics for high-risk raids from 2001 onward.[51] Deployments continued until the 2013 withdrawal of combat troops, with 40 Commando involved in the final Marine rotations securing key areas.[3]Controversies and Criticisms
Malayan Emergency Incidents
During the Malayan Emergency, members of 40 Commando Royal Marines were photographed posing with the severed head of a Malayan National Liberation Army (MNLA) guerrilla killed in combat, an image that contributed to the 1952 British Malayan headhunting scandal.[52] 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 bounty payments and intelligence purposes, amid broader counter-insurgency tactics employed by British forces.[53] The photograph, depicting soldiers in a 40 Commando base handling the head, was published on the front page of the Daily Worker on 28 April 1952 under the headline "This is the war in Malaya," sparking public outrage in Britain and accusations of barbarism.[52] 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.[53] 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.[52] 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.[53]Operational and Training Disputes
In 2005, a video emerged depicting an initiation ceremony for new recruits to 40 Commando at their base in Taunton, Somerset, showing marines engaged in naked wrestling in mud, being pelted with eggs, and other humiliations described by participants as "letting off steam."[54] The Ministry of Defence maintained that such activities did not constitute bullying and were not indicative of unit policy, despite public and media scrutiny prompting a criminal inquiry into allegations of violent bullying within Royal Marines units, including footage of a marine being beaten unconscious.[55][56] Further incidents in 2016 involved three marines from 40 Commando near Taunton sentenced to detention for a "depraved" initiation ceremony where a recruit was forced to drink from a mess tin filled with urine and vomit from a paddling pool, alongside other humiliations lasting 40 minutes.[57] Senior officers were criticized for failing to intervene in related "reefing" 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.[58][59] These events highlighted ongoing concerns about hazing 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 Mojave Desert sparked a public dispute when British media reported that 40 Commando had "dominated" a US Marine Corps unit, eliminating nearly all opposition and forcing a surrender midway through, prompting claims of superior tactics and realism in Royal Marines training.[60] US Marine Corps officials rebuffed these accounts, stating no unit 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.[61] This exchange underscored tensions in allied training narratives, with UK sources attributing success to innovative "special operations capable" approaches adopted by 40 Commando, while US responses prioritized factual correction over competitive framing.[62]Achievements and Recognitions
Battle Honours and Decorations
40 Commando, as a unit of the Royal Marines, shares the Corps' singular battle honour for the capture of Gibraltar in 1704, represented by the globe and laurel device on their cap badge and colours; unlike British Army 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.[63] One such date for the Corps, involving 40 Commando's leadership, is 20 March 2003, marking the rapid seizure of the Al Faw peninsula in southern Iraq during the opening phase of Operation Telic, where the unit advanced under fire to secure oil infrastructure and enable subsequent coalition operations.[63] 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 Brunei Revolt and Borneo confrontation, where 40 Commando conducted patrols and civic actions to support local populations against insurgent threats.[64] The most recent, in April 2019, honoured their 2017 deployment to the Caribbean, delivering aid to over 1,000 hurricane victims in Montserrat and the British Virgin Islands after Hurricanes Irma and Maria devastated the region, including engineering repairs to infrastructure and medical evacuations.[65] Individual members have earned gallantry decorations for valour in combat, particularly during the Second World War and Malayan Emergency. Notable Military Medals include:| Recipient | Award | Campaign and Date | Details |
|---|---|---|---|
| Corporal James Gorman | Military Medal | Italy, Garigliano River crossing, 1944 | Recognized for courage, leadership, and resourcefulness enabling the advance across the river under enemy fire.[66] |
| Sergeant Basil Aylett | Military Medal | Second World War operations with 40 RM Commando, 1943–1945 | Awarded for gallant and distinguished service in multiple engagements.[67] |
| Corporal Peter Dale | Military Medal | Malayan Emergency, 1 July–31 December 1951 | Honoured for gallantry in counter-insurgency patrols against communist guerrillas.[68] |
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 Basra, thereby contributing to the swift collapse of regime control in southern Iraq.[4] Similarly, in the initial 2001 deployment to Afghanistan, 40 Commando secured Bagram Airfield on October 7, establishing a critical logistics hub that supported the subsequent influx of international troops and operations against Taliban positions.[69] These actions exemplify the unit's role in validating amphibious and expeditionary doctrines emphasizing littoral maneuver and pre-emptive strikes, influencing Royal Marines' prioritization of versatile, sea-based power projection 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.[70] 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 Future Commando Force 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 strike companies for Littoral Response Groups, which enhance persistent presence in contested maritime domains.[1] [9] This evolution reinforces the strategic imperative of light, technology-integrated forces for crisis intervention and deterrence, with 40 Commando at the vanguard of integrating surveillance and precision strike capabilities to outpace peer adversaries.[71]Leadership and Traditions
