Sir Archibald David Stirling, was a Scottish officer in the British Army and the founder and creator of the Special Air Service (SAS). Under his leadership, the SAS carried out hit-and-run raids behind the Axis lines of the North African campaign. He saw active service during the Second World War until he was captured in January 1943. He spent the rest of the war in captivity, despite making several attempts to escape.

The Special Air Service (SAS) is a special forces unit of the British Army. It was founded as a regiment in 1941 by David Stirling, and in 1950 it was reconstituted as a corps. The unit specialises in a number of roles including counter-terrorism, hostage rescue, direct action and special reconnaissance. Much of the information about the SAS is highly classified, and the unit is not commented on by either the British government or the Ministry of Defence due to the secrecy and sensitivity of its operations.
