The Dirty Dozen

During World War II, a rebellious U.S. Army Major is assigned a dozen convicted murderers to train and lead them into a mass assassination mission of German officers.
12 American military prisoners in World War II are ordered to infiltrate a well-guarded enemy château and kill the Nazi officers vacationing there. The soldiers, most of whom are facing death sentences for a variety of violent crimes, agree to the mission and the possible commuting of their sentences.
