The Inglorious Bastards 1978

If you're a kraut, he'll take you out!

Directed by Enzo G. Castellari

Set in Europe during WWII, a group of American soldiers on their way to military prison are beset upon by a German artillery attack, escaping with Switzerland in their sights. Before making it any farther, they volunteer to steal a V2 warhead for the French Underground - taking them deep into the heart of German territory.
