Meanwhile StuG III Ausf E front plate 50 mm in reality, 150 armour value in game.
Apparently Relic have no idea what slopped armor is:
http://en.wikipedia.org/wiki/Sloped_armour
"Sloped armour is armour that is neither in a vertical nor a horizontal position. Such "angled" armour is often mounted on tanks and other armoured fighting vehicles (AFVs). Sloping an armour plate makes it harder to penetrate for antitank-weapons, such as armour-piercing shells (kinetic energy penetrators) and rockets, if they take a more or less horizontal path to their target, as is often the case. The better protection is caused by three main effects."
I know it's only an arcade game not a simulator but in my opinion in CoH2 T-34s and Shermans are to fragile in comparision to PzIV + there is imbalance with AT infatry weapon.
Also I don't know if they changed it but grens Panzerfaust was autoctit for the engine while cons AT greanade had only a chance to damage the engine.
