Continuity mistake: As the Dirty Dozen ready for the wargames, they are in a truck passing and saluting a line of American light tanks in closeup. Immediately after turning left into a circular driveway and stopping, in a long shot the tanks have quickly turned into a long line of Army trucks. There was no time for the tank convoy to drive off and have a convoy of trucks enter the scene.
Gen. Denton: Major Reisman is heading toward a court martial of his own. He's the most ill-mannered, ill-disciplined officer that it's ever been my displeasure to meet.
Maj. Gen. Worden: You think so, Denton? You may be right. But he's sure right about one thing. Somebody up there must be a raving lunatic.
Trivia: We never actually see Posey (Clint Walker) die on film. We know where he is during the mission and we only saw his partner Bravos get shot but not Posey. I always have this funny feeling that he may have survived and the surviving members (Lee Marvin, Charles Bronson, and Richard Jaeckel) of the Dozen forgot about him.
