Note: I watched the "Reconstruction version."
Only the 2nd Samuel Fuller film I've seen (the other being Pickup on South Street), and The Big Red One hit me much stronger than the first did. One of the better war movies from the "platoon" perspective, the gold standard being to me Battleground. Some of the cast works better than others, and Lee Marvin is a great anchor. I can see Spielberg being influenced by this (along with Battleground) for Saving Private Ryan. Some very interesting scenes and moments.
