The Dirty Dozen

An Army Major who likes to butt heads with his superiors, is being 'given' a new assignment, to train 12 men who are either sentenced to death or life imprisonment, to go behind enemy lines raid a chateau that the Germans are using as an rest center and kill as enemy officers as they can and disrupt the German chain of command. Now he not only has to train them; he has to get them to start acting like a unit. And when a Colonel whom the Major has been having the most trouble with reports to the Generals that his unit is not working out, the Major asks the General to try them out by having them participate in a war game. If they don't succeed they will be sent back to prison to face their sentences.
