Military of the Falkland Islands

The Falkland Islands are a British overseas territory and, as such, rely on the United Kingdom for the guarantee of their security. The other British territories in the South Atlantic, South Georgia and the South Sandwich Islands, fall under the protection of British Forces South Atlantic Islands (BFSAI), formerly known as British Forces Falkland Islands (BFFI), which includes commitments from the British Army, Royal Air Force and Royal Navy. They are headed by the Commander, British Forces South Atlantic Islands (CBFSAI), a brigadier-equivalent appointment that rotates among all three services (Navy, British Army, and RAF).

Argentina invaded and took control of the Falklands on 2 April 1982. After recapturing the territory in June 1982, the UK invested heavily in the defence of the islands, the centrepiece of which was a new airfield at RAF Mount Pleasant, 27 miles (43 km) west of Stanley. The base was opened in 1985, and became fully operational in 1986.

Falkland Islands Defence Force

The Falkland Islands maintains its own part-time volunteer force, the Falkland Islands Defence Force (FIDF), previously known as the Falkland Islands Volunteer Corps. Although this unit existed in 1982 as a reinforcement for the Governor's detachment of Royal Marines, it did not play any part in the main conflict during the war of 1982, its members having spent the duration of the hostilities under house arrest by the Argentines after their surrender on the Argentine capture of the islands. The FIDF is now a platoon to company-strength light infantry unit with a permanent training Warrant Officer seconded from the Royal Marines. The FIDF operates in a number of roles and is fully integrated into the defence scheme for the islands.
