The IS-7 started as OBJ.260 from previous IS-5 which failed terribly, it was the most heavily armoured and technologically advanced heavy tank in the world at that time, the IS-7 has a 130mm stabilized cannon fed by an autoloader , 8 machine guns, and up to 300mm of armour, it was the largest tank that the USSR (Soviet Union) had or ever produced. The tank had a pike nose and the upper plates were 150mm thick and angled at 60 degrees, the lower glacis plate was 100-120mm with a slight angle obviously in world of tanks only able to reload in neutral position is not applicable because it’s a game, so don't worry about the relaod system.
