A couple of observations on SPR.
1. By June 44 a lot of the German units were not rock solid with experience as they had been a couple of years prior. Five years of war and some big defeats had knocked them around quite a bit. Recruits were coming into the ranks that, in 39, would have been discarded.
2. Armour is at a distinct disadvantage in the narrow confines of village streets. Experienced soldiers with the right weapons can exact a heavy toll on armour, way out of proportion to their numbers.
Spielberg got it mostly right for me, especially the background battlefield noise which Hollywood had never been able to get right. The only thing missing was that particular smell that emanates from the battlefield but is impossible to duplicate in a picture theatre.
