Revealing mistake: In several scenes when they show the front of the barrel of the German machine gun you can see the "blank adaptor" inside the barrel. This is inserted to not allow the gas from the cartridge to escape out the barrel but "blow back" the bolt and insert another round.
Combat! (1962)
1 revealing mistake in The Glory Among Men
Starring: Vic Morrow, Jack Hogan, Pierre Jalbert, Rick Jason
Audio problem: Season 3, Episode 68, "The Duel". Sometimes the tank's co-axial machine gun is firing, but no gunfire sound is heard.
Braddock: Don't just stand there sucking on a prune pit, get these men some water.
Trivia: Actor Vic Morrow used a non-firing wooden replica of a Tompson submachine gun due to its lighter weight, thus being easier to carry. He used a heavier blank-firing model when it was required to be fired.
