An initial glance makes it seem like this one is worth watching, although the part I grazed through, with a Soviet attack, did make it seem like it suffers from “Nazi Banzai Syndrome”.
For the most part, the Germans in these movies, and in SPR as well, get the horde treatment, when part of the reality of what made them so dangerous is how good they were at the infantry tactics game.
You are correct about infantry tactics.
But, part of the horde treatment must also result from the atrocities they committed against civilians in both WW1 and WW2.
I know. The Russians used human-wave assaults throughout the war, the Germans not so much. The enormous disparity in casualties bears this out.
