The United Kingdom Commando Force (UKCF), previously called 3 Commando Brigade, is the special operations commando formation of the Royal Marines. It is composed of Royal Marine Commandos and commando qualified personnel from the Royal Navy, British Army and Royal Air Force.
The brigade was formed 1 September 1943 at Dorchester with personnel from 102 RM Brigade, during the Second World War, with a mixture of Army Commando and Royal Marine Commando units, and was deployed to the South-East Asian Theatre of World War II to conduct operations against the invading forces of Imperial Japan, such as the Burma Campaign. After the Second World War, the Army Commandos were disbanded and the brigade became a Royal Marine formation. Recently, United Kingdom Commando Force has again become a mixed formation with the addition of commando qualified soldiers from the Royal Artillery and Royal Engineers to provide support for the Royal Marine Commandos. Since the end of the Second World War, it has been involved in a number of engagements such as the Suez Crisis, Falklands War, Gulf War and the War in Afghanistan.
