The Special Air Service (SAS) is a special forces unit of the British Army. The SAS was founded in 1941 as a regiment, and later reconstituted as a corps in 1950. The unit undertakes a number of roles including covert reconnaissance, counter-terrorism, direct action and hostage rescue.

The corps presently comprises 22 Special Air Service Regiment, the regular component under the operational command of United Kingdom Special Forces, and 21 (Artists) Special Air Service Regiment (Reserve) and 23 Special Air Service Regiment (Reserve), which are reserve units under the operational command of 1st Intelligence, Surveillance and Reconnaissance Brigade.

The Special Air Service traces its origins to 1941 and the Second World War. It was reformed as part of the Territorial Army in 1947, named the 21st Special Air Service Regiment (Artists Rifles). The 22nd Special Air Service Regiment, which is part of the regular army, gained fame and recognition worldwide after its televised rescue of all but one of the hostages held during the 1980 Iranian Embassy siege.

The Special Air Service was a unit of the British Army during the Second World War that was formed in July 1941 by David Stirling and originally called "L" Detachment, Special Air Service Brigade—the "L" designation and Air Service name being a tie-in to a British disinformation campaign, trying to deceive the Axis into thinking there was a paratrooper regiment with numerous units operating in the area (the real SAS would "prove" to the Axis that the fake one existed). It was conceived as a commando force to operate behind enemy lines in the North African Campaign and initially consisted of five officers and 60 other ranks. Its first mission, in November 1941, was a parachute drop in support of the Operation Crusader offensive. Due to German resistance and adverse weather conditions, the mission was a disaster; 22 men, a third of the unit, were killed or captured. Its second mission was a major success. Transported by the Long Range Desert Group, it attacked three airfields in Libya, destroying 60 aircraft with the loss of 2 men and 3 Willys MB. In September 1942, it was renamed 1st SAS, consisting at that time of four British squadrons, one Free French, one Greek, and the Folboat Section.
