In 1952, SBS teams were held at combat readiness in Egypt in case Gamal Abdel Nasser's revolution turned more violent than it did. The SBS were also alerted during the Suez Crisis of 1956 and coup against King Idris I of Libya (1959), but in both cases they did not see action. In 1961, SBS teams carried out reconnaissance missions during the Indonesian Confrontation (see Operation Claret). In the same year, Iraq threatened to invade Kuwait for the first time, and the SBS put a detachment at Bahrain. In 1972, the SBS came into prominence when members of a combined SBS and RAOC team parachuted into the Atlantic Ocean after a bomb threat on board the cruise liner . A thorough search of the ship found no evidence of any device drawing the conclusion that it was a hoax. The SBS conducted operations in Northern Ireland during The Troubles including with submarines. In January 1975, two SBS kayak teams were inserted from HMS "Cachalot" to conduct an anti gun running operation in the area between Torr Head and Garron.
