The Israeli government was persuaded at the last minute not to enter the Gulf War when they were told that it was the SAS who were hunting for Scud missiles and disrupting Iraqi communications. The SAS forces inside Iraq comprised two half-squadrons (30 men each with vehicles) and three much smaller foot patrols, one of which had the call sign, Bravo Two Zero. Corporal Terence Clayton, known as Yorky, was a member of one of the half-squadrons. His group played a crucial role by destroying microwave communications lines, Scud missiles, weapons dumps and Iraqi soldiers. His 42-day story ricochets between stunning successes and extraordinary cock-ups, moving from corpse-strewn battlefields to stealthy operations at the dead of night.
