Ways to engine play with the USSR in 4.3

i don´t know but almost all the tanks have the same firepower and almost the same armor so I kind of bore when I play with them, some recommendations to play it on RB?

You mean the 31 flavors of T-34?
Alternate with the 57 flavors of Sherman…

ok

The kv-1s are pretty good, if you wanna play heavy tanks
