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.

General Randy Badger arrives from America on official duty. He enlists Gary and the boys, and instigates his own mission - to drink beer, see strippers and find his Scottish ancestors, the McBadgers. Hoo ya.

Gary goes to St Andrews for a debate against a formidable opponent. He has been briefed on what to say, but when he takes the stage, he surprises everyone, including himself.

Gary complicates a training exercise by agreeing to pick up a cooker for his Dad. Collecting it with a tank is one thing - hiding it from the sergeant is another.

Gary and Charlie are on guard duty on Gary's birthday. Charlie starts a rumour about himself that gets out of hand, and Gary's determination to enjoy his birthday is tested by some awful presents and unexpected guests.
