there is that film iron cross about german soldiers. i haven't seen it
but you could make a parable style film about nazi soldiers who are normal lads who go to war and one of them gets killed. of course they wouldn't dare, but it's not to say that they couldn't or shouldn't
letter from iwo jima showed an incredibly sympathetic portrayal of japanese soldiers who were just as bad as the nazis, probably worse, admittedly in that battle they weren't, but it does make the japanese army look very much the honourable normal guys suffering from the insanity of war....
