The APBT was the first
special forces division created in
South America. The unit was established in 1952 on board LST ARA
Cabo San Bartolomé with instructors who were former
X-MAS Italian diver commandos. In those times a reduced Tactical Divers Group was operating in the
Cabo San Bartolomé; years later the
Navy created a second group assigned to the Escuadra Naval del Plata. In 1966 both services were merged, creating the actual Tactical Divers Group. In the
1982 invasion of Islas Malvinas, the main landing at
Yorke Bay to the east of
Port Stanley on 2 April, was preceded by an
amphibious reconnaissance party of the APBT. They had been landed by the submarine
ARA Santa Fe. They successfully secured the beach and the lighthouse, and set up beacons to guide the amphibious vehicles of the assault group, which had disembarked from the landing ship
ARA Cabo San Antonio some distance offshore. Some sources assert that
Buzos Tácticos units attacked the
Moody Brook barracks and besieged
Government House, however these troops were mainly units of the
Amphibious Commandos Group (
Agrupación de Comandos Anfibios, APCA). The error was due to hearsay reported by a journalist from the Argentinian magazine
Somos, which was the first to publish an account of the operation, although a number of individual APBT members assisted the Commandos in both actions, specially around Government House. Both the APBT and the APCA teams had returned to Argentina by nightfall, on the same aircraft which had brought in the first
Argentine Army reinforcements. == Organization and training ==
