The Special Air Service of New Zealand (NZ SAS) was formed in June 1955 as an elite New Zealand unit capable of special missions. It was modeled on the British Special Air Service (SAS)
The SpecialAirService (SAS) is the principal special forces organisation of the British Army.
During the Falklands War 1982, SAS teams worked, with their Special Boat Service counterparts, in many operations before the main force landings at San Carlos and after the landings ahead of the FEBA (Forward Edge of Battle Area- the front line).
U.S. - The U.S. Army's Special Operations Forces' Delta Force was formed based along SAS organizational patterns, and in many ways, the U.S. Navy's SEALs' Team SIX (the SEAL Team specifically tasked with counterterrorism operations) was based on the SAS model.
The SpecialAirService (SAS) is the principal special forces organisation of the British Army and probably one of the most recognised (for its oustanding success) military organisations in the world.
In the SAS, the men of the Air Troops are known as "Ice Cream Boys", due to their tans and the sunglasses they often wear.
NewZealand and Australia have their own SAS units.
