Argentine special forces invaded the Falkland Islands, sparking the Falklands War against the United Kingdom.

Argentine forces invaded the Falkland Islands on 2 April 1982 in a military operation code-named Operation Rosario. The invasion served as a catalyst for the subsequent Falklands War. The Argentines mounted amphibious landings and the invasion ended with the surrender of Falkland Government House.

The Falklands War was a ten-week undeclared war between Argentina and the United Kingdom in 1982 over two British dependent territories in the South Atlantic: the Falkland Islands and its territorial dependency, South Georgia and the South Sandwich Islands. The conflict began on 2 April 1982, when Argentina invaded and occupied the Falkland Islands, followed by the invasion of South Georgia the next day. On 5 April, the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with an Argentine surrender on 14 June, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders were killed during the hostilities.
