Well hello there!
It is but a simple suggestion for the sake of some individuality and an extra favour of historical accuracy. The Soviet Engineer squad in the Berlin campaign can create an AT gun which is currently modelled as the German 7.5 cm Pak 40. While it is completely possible and realistic that the Soviets use captured weapons, see the AT squads using Panzerfausts, I would suggest replacing said gun with the model of a 76.2 mm ZiS-3, a more prevalent Soviet anti-tank/divisional gun. There are multiple historical photos and film reels of these guns being used in Berlin, even firing at buildings at point-blank range.
I believe it would be good as a minor cosmetic change just to enhance the immersion.
What is your opinion, fellow gamers?
