Continuity mistake: After McCall shoots the German soldier dead, the German's body changes from lying face up to face down. Also, the dead German's helmet, which was lying two feet away, is now nestled next to the German's head.
Continuity mistake: When The Squad consolidates after the battle in the village, Cully has his rifle unslung and is holding his helmet in the close ups, while in the long shots Cully is wearing his helmet and his rifle is slung on his right shoulder.
Factual error: McCall shoots a German ten times with his M1. But the M1 could hold only eight bullets.
