Revealing mistake: After the accident with the German car crashing into the pile of snow in which the Germans were killed, Schaffer first hangs an MP40 on his shoulder and then somehow pulls up a body with only one hand. And with the changing of the grip, (from chest to legs) the 'body' stands on his own feet to give Schaffer the time and opportunity to do it properly. (00:50:10)
Suggested correction: Schaffer uses two hands to pick the body up his left hand grabs the body's right arm and his right hand grabs the body's tunic (under the body's chin).
Revealing mistake: Except for the one that crashes, every single helicopter in this film is 100% factory fresh, brand new - no mud spatters, no scratched paint, not a dent or a blemish anywhere. They look like they just rolled off the production line. Strange that, on the front line in a war zone and all.
Revealing mistake: When Buck and the gang ride away from the saloon in Dallas where JC made a few new 'friends', the footage is sped-up for a second just as soon as James Caan jumps on his horse. (00:05:50)
