During chapter 9. Starting at 47min. 47sec. to 47min. 51sec. The Nazi shield takes one of the Americans right off the deck of the sub killing him. The shield came off the American sub across from them. The one Bill Paxton was Captain of. The shield as you no was put on earlier when they unvalled it. The problem is after the shield fly's off. They cut to a scene of the American sub in flames. Look closely. WHOOP's there's that shield again. Right where it was when it was unvalled.
