Improving German vehicles

LiannaSilverwind: IS-7 frontal armor is very poor as was proved many times at Russian forum, including videos and tests of penetration via different amount of cannon at different range. In fact many players consider IS-7 being heavy medium tank, not heavy tank, due to its poor frontal armor. As was mentioned above, IS-7 frontal armor has one big weakspot, properly used by every opponent, if IS-7 driver is unable to fight hulldown.
Ural Steel championship proves that Maus tank are far from being extinct, because most teams use them, the same with IS-7 and T30. Same was proved in league before.
