USSR

While several tanks from the USSR tend to have thinner armor, they make up for it by having it heavily sloped which increases its effective thickness and gives them a higher chance to ricochet an incoming shell. Their guns also pack the most punch in the game and that, along with their good speed, maneuverability and armor characteristics makes them kings of close combat. Their downside is that they have poor accuracy and aim time, in some cases they have a bad rate of fire, they are prone to ammo rack detonation and sometimes engine fires.

Soviet light tanks are typically the fastest in the game and, like most Soviet tanks, have a small frontal profile and sloped armor.

Soviet medium tanks are also fast and maneuverable, but in order to make the tanks compact, engineers placed ammo storage in very vulnerable places, increasing the chance of ammo rack detonation.

Soviet heavy tanks have the best values for everything except accuracy and aim time; their frontal armor thickness and slope makes them quite difficult to penetrate from the front.

Soviet tank destroyers are not as well armored or accurate as their American or German counterparts, but they offer increased speed, agility, and brute firepower.

Soviet self propelled guns are generally quite accurate but don't do much damage. However, they also generally fire their shells in a very high arc, making their flight time long, but able to hit tanks hiding behind rocks and small buildings. They also tend to have higher firing rates than their foreign counterparts.
