Out on the streets of Colchester, the RMP seek to impose some military discipline on a crowd of drunken brawlers. Meanwhile, one young soldier must face up to his relationship with alcohol after being found drunk on duty in a war zone.

It can cost upwards of £70,000 to train an infantry soldier, and an important task for the staff of the Military Corrective Training Centre is to retrain and reinvigorate those detainees re-joining their units as soldiers after they've broken the law.

A detainee found guilty of indecent misconduct is treated with a lack of respect by other detainees, and there's an allegation of domestic violence in Merville Barracks.
