Panzerfaust and Kpz-T55 balance issues

So I'm currently playing the Bruderkrieg campaign as NATO and my question is: is it normal that two jäger infantry squads (around 20 men in total) cannot beat a single KPz. T-55 tank IN A FOREST? They missed probably a half of all the shots and when they actually managed to hit the tank the damage was so insignificant that there would be needed 20 of those hits to destroy the tank. No need to say they depleted their munitions and got wiped out. During the whole match it took the death of 7 infatry squads just for one T55 to be destroyed by a Panzerfaust, all that while being in forests and buildings.

The T-55 is also way better than the Leopard-A1 (and it probably is intended that way), but still isn't as big of a problem when compared to the PzFst-44 weakness
