One of the AWOL soldiers is a paratrooper from the 82nd Airborne Division. He wears the correct airborne-style helmet, which has a chin cup and extra reinforcing straps. The other GI is a regular ground infantryman whose helmet should have a standard, simple strap with no chin cup. However, he too is wearing an airborne helmet.
In the building, the .45 Automatic shown has a hooked trigger guard and is painted black. The trigger guard on the real pistol is rounded and does not have a hook or finger rest in front.
When the soldiers are captured by the MPs, they are driven in a jeep from the early Fifties, not a WWII Willys jeep.
In the scene where the two AWOL GI's first encounter the partisan and his wife, one of the soldiers cautiously holds the couple at gunpoint while trying to identify them. But as different angles are shown of this scene, the GI's pistol changes from a U.S. M1911A1 semi-automatic to a German P.38 semi-auto, then back to a U.S. M1911A1.
Deming smashes up the face of the MP and swaps dog tags so that it will appear that he is dead. However, given that he does not change the uniform or helmet and only places the tags on the body and not around the neck), it is still possible that the body will not be identified as his.
