Corrected entry: When Winters is in his office and Nixon is telling him he's off to Paris, there are three people present, Richard Winters, Lewis Nixon and Harry Welsh. At the very end of the scene, someone says "Second that" but the subtitles say BOB: "Second that." There is no-one in the room called Bob.
Corrected entry: In part 5, Crossroads, when they are firing on the Polish and the SS companies, you see the left side of the 30-cal machine gun. As it fires you see shells dropping out of the outer side. This shouldn't happen because that would indicate a disintegrating belt, but they didn't come into use until the 1960's so the rounds from the gun should be in a belt.
