But consider that the Americans had overwhelming mobility and speed by 1945. They also had radios and by 1945 the U.S. army was well experienced in communicating and coordinating attacks. The preview also seems to tell us, or at least suggest, that they have intelligence knowing that a German attack is coming. But whatever, ugh. I guess I'll take the bait and go see the movie sometime this coming week. But I fear its going to be like a WW2 movie version of "Gravity". Cool visuals, action, a big Hollywood star, maybe a story...but ultimately not credible or believable.
