Britain's Special Air Service is the special forces regiment upon which all others are based. Its men comprise some of the most skilful, highly trained and motivated soldiers in the world. They will be expected to perform the most difficult and hazardous military missions - and to win through against the odds. This is how the SAS does it...

In wartime, the primary role of the SAS is intelligence gathering. Small specialist teams go behind enemy lines secretly to gather information for future offensive operations.

Using ex-SAS men, SAS SURVIVAL SECRETS: BEHIND ENEMY LINES is a vivid and detailed recreation of a typical mission. Inserted by boat, a four man patrol set up an offensive Observation Post close to an enemy base. Their mission: to gather intelligence and to 'take out' a maverick General. After a daring sniper attack, the team must break for their extraction point but experience almost constant close contacts with enemy forces. As casualties mount, escape seems almost impossible.

SAS veteran Eddie Stone explains his patrols weaponry, combat options, evasion and survival tactics. From surviving interrogation to emergency battlefield medicine, they provide the closest insight yet into what it's like to be an SAS man fighting to survive behind enemy lines...
