That movie is just another piece of war propaganda and it is actually pro war and also pro war crimes.
Rob Ager made a few very good videos about it, like for example that dying Germans wouldn't scream, but US soldiers are. Germans are not portrayed as humans.
And in fact the movie goes from pseudo-realistic portrayal (*), to comical nonsense.
Lesson learned "better kill the enemy whenever you can, otherwise the enemy will get back at you", not unusual for war propaganda.
(*) to my knowledge Nazis forced young German teenagers to operate the MGs at that place, because there were not many others left. They had the enemy in front (US soldiers) and another enemy in the back (Nazis). If the movie would have shown that, it would have shown the true horror.
But instead, nope. German soldiers as skin headed 35-40 year olds, which is bollocks to my knowledge.
