Factual error: When the soldiers return to HQs, the American flag, hung vertically over the entrance, has the blue field with stars on the right. The flag, when hung vertically, is supposed to have the blue field on the left..
Factual error: The commanding SS officer at the church massacre is incorrectly addressed "Herr Major". Although his rank does correspond to that of a Wehrmacht major, the correct address is "Sturmbannführer" (and not with "Herr", in the SS officers were addressed with rank only).
Factual error: During the first battle both sides uses artillery, however none of the guns have any recoil when firing. Neither the American M101A1 or the German 88 mm Flak were recoilless cannons - both cannons' barrels would have recoiled backwards when fired.
