Acronym for the Special Air Service, an elite British commando team (similar to the US Delta Force) that, in Ministry of Defence war games, is assigned the mission of defending a top-secret radar station on Gibraltar against three double-0 agents in the pre-credits teaser of The Living Daylights. Unfortunately, an enemy agent penetrates their security and kills 004 (Frederick Warder) and several SAS men before Bond (Timothy Dalton) gets just revenge.
