Factual error: In the end scene on the pier, Robert Duvall has Michael Douglas at gunpoint. A closeup of the revolver's chambers shows them to be empty of bullets; yet Duvall then shoots Douglas dead.
Factual error: The Germans encounter three enemy tanks, all Russian T-34/85 models that were introduced in mid-1944. Additionally, they shoot at the tanks with an anti-tank gun which is painted sand colour. This colour was not introduced until Feb 1943.
