soviets have too many troop to the front already they are OP!
I'm pretty sure Soviets move as fast as other soldiers, yet all other factions get transport for their men. Why not the USSR? Just make it cheap, crappy and prone to exploding with one shreck hit.
They move faster. They hahe a 2nd retreat point ant free charge abilities.
Why not USRR you ask? Becouse its industry was entirely focused on building tanks and stopped building trucks in 1942. Soviet army had very poor logistical support, its tanks carried much more fuel becouse of that, even some elite guards divisions were cavalry. US leand leased trucks were never frontline units.
