Gary: Tank Commander S03E02 - Good Exercise

Gary delights Captain Fanshaw by 'saving his life' on a competitive skills exercise. With the enemy being led by his father, Colonel Fanshaw, the Captain is so grateful that while the others are fending off the Colonel's increasingly audacious attacks, he offers Gary a new job that sounds too good to be true - and turns out to be exactly that. Under the piercing gaze of Sergeant Thomson and with the rest of the team dropping like flies, it's up to Gary to somehow win the task - without impressing the Captain.
