Trivia: Notice how the only survivor (Bronson) isn't a "real" Criminal (rapist, murderer etc) but shot a soldier running off with the unit's medical supplies. The Hollywood Code of the time couldn't show criminals "getting away with it."
Suggested correction: Joe Stern, Eric "Swede" Wallan, Ernesto "Pops" Ferucci, and Francis Kelly survive.
Continuity mistake: In the wargames scene, right after the group comes down the hill with the live artillery fire, they change arm bands from blue to red. In the next scene when they pick up the stolen jeep, everyone is wearing blue arm bands again (when they went over the hill, they were in red territory so would not have changed back to blue while walking to meet the jeep). Then when they crash the jeep, they are back in the red arm bands for the remainder of the scene.
Suggested correction: The road they were on was not in red territory, which is why everyone in the jeep was also in blue. That's why Joseph was asked what he was doing on the road and the doctor in the ambulance said he had permission to cross all lines and roadblocks.
Continuity mistake: When Waterslaw and Jefferson each shoot a soldier through a window, no glass seems to break until we see each soldier fall out through the glass.
Suggested correction: Windows weren't then made of safety glass which shatters on impact. Plain old tempered glass doesn't shatter unless something heavy goes through it and definitely not with only 1 or 2 bullet holes.
Plot hole: When the Major and Wadislav walk up the stairs in the German mansion they are met by a pair of German officers who say something to them. Wadislav then tells the Major that he couldn't understand a word they said. What they actually said was 'Nice weather, wouldn't you agree?' Wouldn't you think that a man who speaks German well enough to convince the guards in a German HQ would understand such a simple phrase? Wadislav was chosen specifically for his ability to speak some German.
Suggested correction: It might be a reasonable assumption, but it's also possible that he didn't. A character not knowing something that you think they should doesn't make it a plot hole. Regardless, no part of the plot of the film was broken by this; it's an irrelevance.
