The idea of having a force designed for a special purpose dates far back into history and has been used in many wars. However, it is rare, if ever, that these forces meet in combat. Their targets are usually those too difficult to tackle by conventional forces. Or they’re used to exploit weaknesses in conventional forces. In a unique confluence of events though, British SAS and Royal Marine Commandos faced off against Argentine Special Forces during the Falklands War of 1982.
The fighting (neither side actually declared war) started on Apr. 2, 1982, when Argentina invaded the Falkland, South Georgia, and South Sandwich Islands. Argentina took this bold move due to a longer simmering dispute over the sovereignty of the islands.
The British response was swift and soon a naval task force was steaming towards the Falklands.
They landed in force on May 21, 1982, to retake the islands. The operation, codenamed Operation Corporate, was spearheaded by 3 Commando Brigade with paratroopers from 2 Para and 3 Para attached.
The elite 3 Commando Brigade consisted of 40, 42, and 45 Commando, the equivalent of three infantry battalions, along with Royal Marine artillery and engineer support. The British Special Forces contingent consisted of the 22nd Special Air Service Regiment as well as cadre from the Mountain and Arctic Warfare school.
