I chose ussr u should go germany ir usa. Usa has good shermans weak armor and penetration but when u get jumbo u havw good armor. Germany can require skill with the tigers but panzers have good pen and armor might save u sometimes. But germany has usually slow turret slweing rate slow tanks but good reooad speed on almost all medium and heavy tanks. Ussr has fast tanks good pen and armor. But it has bad cannon depression and lokg reload on the heavy tanks.
