Corrected entry: In the final shootout, the GIs are using at least one semi-automatic American M1 Garand rifle. It is never explained where they got this from, as all they had before were captured German bolt-action Mausers. They are escaped POWs and have been stripped of their own weapons. They have encountered no American corpses or vehicles except an ambulance, which they specifically state has been stripped of everything of use. At one point Gould actually says all they have is a "bolt-action".

Correction: The escaped POW's ambush a German vehicle at the French woman's home. They found a cache of weapons in the back, including the Garand. It's not unreasonable to think that the Germans had taken a Garand off a dead/wounded/captured American or simply found one somewhere.
