After the Second World War the army commandos were disbanded and the brigade became a Royal Marine formation . Recently the Brigade has again became a mixed army and marine formation with the addition of an army infantry battalion , artillery regiment and engineer regiment alongside three Royal Marine battalions and support services . Since the end of the Second World War it has served in the Suez crisis , Falklands War , Gulf War and the War in Afghanistan . History . 3 Commando Brigade can trace its origins back to World War II , when it was formed as the 3rd Special Service Brigade . The Commandos were formed as forces to perform raids on occupied Europe . Many of these raids were relatively small affairs , but some were very large , such as the 1942 Dieppe Raid , and the attack on St . Nazaire to cripple the dry dock there . The 3rd Special Service Brigade was formed in 1943 and sailed for the Far East and saw action against the Japanese in the Burma Campaign . On 6 December 1944 the brigade was re named 3rd Commando Brigade , removing the hated title " Special Service " and its association with the German SS . In January 1945 they were involved in the battles to secure the Myebon peninsula and Kangaw , holding a key position during the battle of Hill 170 against repeated Japanese attacks . The brigade was then withdrawn to India to prepare for the amphibious assault on Malaya , but the dropping of the atom bomb s on Japan ended the war before the planned invasion . Instead the brigade moved to Hong Kong to secure the Crown Colony . In 1946 the Army Commandos in the brigade were disbanded and the brigade became a Royal Marine Commando formation . Post World War II . 3 Commando Brigade was at the forefront of many actions over the next 25 years , acting as a strategic reserve for the Far East and Mediterranean areas . Its most high profile operation during this time was the Suez Crisis , when it took part in the amphibious assault against Egypt ian targets . During Operation Musketeer , units of the brigade made the first British helicopter - borne assault in history . 1971 saw the withdrawal of British forces from the Far East and Persian Gulf . The brigade returned to the UK with other British units . It moved to Stonehouse in Plymouth , where it remains to this day . Operation Corporate . The brigade ' s next large operation was in 1982 . Argentina invaded the Falkland Islands , and 3 Commando Brigade , reinforced by 2 Para and 3 Para , was one of the two main British land formations that took part in operations to recapture the islands . The Brigade landed at San Carlos Water and marched across East Falkland to Stanley . Argentine units were defeated in several sharp engagements , and their forces surrendered on 14 June . Gulf War . In the aftermath of the Gulf War , the brigade was deployed on a non - combat task in northern Iraq . The Kurds had suffered immensely during the war and its immediate aftermath , and the brigade was used due to its rapid deployment ability . It provided humanitarian aid to the Kurds and saved many from starvation . 21st Century . Recently , the brigade has been involved in two major campaigns , including Operation Veritas in Afghanistan , 2001 and 2002 , and Operation Telic during the 2003 invasion of Iraq . In Afghanistan , no contact was made with enemy forces , despite contrary predictions . Iraq , however , saw heavy fighting occur in the early stages of the campaign , as the brigade made its first amphibious assault in over 20 years by landing on the Al - Faw peninsula in south east Iraq . Both operations were successful , and demonstrated the brigade ' s ability to perform its traditional role as one of the United Kingdom ' s elite fighting forces . In 2006 , the brigade returned to Afghanistan on Operation Herrick , replacing 16 Air Assault Brigade , where intense fighting occurred and the brigade suffered a loss of 15 men ( KIA ) . Future . In the future , 24 Commando Engineer Regiment will be removed from the ORBAT not before April 2013 . 131 Independent Commando Field Squadron Royal Engineers will instead be under 32 Engineer Regiment , Royal Engineers ( Army ) and be renamed as 131 Commando Field Squadron Royal Engineers . The Royal Marines 3 Commando Brigade will no longer have 1st Battalion , The Rifles under its operational control . This battalion will move to 160th Brigade under the Army 2020 plan . Organisation . The Brigade is commanded by a Royal Marines Brigadier and contains Royal Marines , Royal Navy , Army and Royal Air Force .
