Yes i have looked at photos, lots of them. The guy looks older than Field Marshal von Paulus. Who was 52.
I'm not trying to make a big deal of it, but that guy is far too old to be a front line German at Stalingrad, he would be fine as a Volksturm in Normandy or Germany. It's not going to stop me loving the game, but it stood out as being peculiar, it's not a big deal it's a nitpick, but it was noticeable.
Here is some photos of German prisoners captured at the end of Stalingrad, i'm sure you agree they look tired and desperate, and would have gone through all of the ageing stress, but you'll notice none of them are like the soldier in that screenshot.
