Continuity mistake: When that one captain is refusing to obey the orders of Nick Nolte he says the time is 13:21 but his watch says it's actually 14:31. Then a couple of seconds later the time is 14:45. Their whole conversation was shown and there was no time in between and it was much shorter than 15 minutes. (01:03:00)
Continuity mistake: As Stavros talks to Lt. Col. Tall about the time, his watch jumps ahead by a couple of hours, and the time he states is not the time on the watch anyway.
Continuity mistake: When the seven soldiers go up the hill to attack the bunkers all soldiers are wearing shirts and carrying six rifles and one Thompson. In the middle of the fight one soldier is wearing a sleeveless shirt and wielding a shotgun. (01:27:46 - 01:35:36)
