Cpl Gary McLintoch and his tank crew return from Iraq to tackle their toughest mission yet - a recruitment stall in the local shopping centre. And when the worst recruit ever is signed up, the boys try desperately to pull off the great escape.

Gary swaps the tank for a Green Goddess as the army covers a firefighters' strike. The boys prepare for their first fire, but when it finally comes, it's their people skills that face the ultimate test.

Gary takes part in a debate about the Iraq War in University of St Andrews against an anti-war student, organised by the OC's annoying brother.

Gary agrees to help his father by buying a cooker for him and collecting it in the tank whilst on exercise. Despite the show's name, this is the first appearance of the tank (actually an AS-90) which Gary commands.

Gary spends his birthday on guard duty. Charlie starts a rumour about himself.
