KV

The KV was a moved Tier V Soviet Heavy Tank. When you reach it, you might feel as if you came out of another world, because the T-28 was so fast, which dramatically changes your tactics here. However, if you give this tank time, you can equip an extremely powerful gun, the 152mm M-10 (known affectionately as the derp gun). When stock, the KV is similar to the KV-1, and when fully upgraded and given the 152mm M-10, it will be a KV-2. The KV was the more popular of the original Tier V Heavy Tank, the other being the T-1 Heavy. Compared to the T-1 HT, it is less mobile but stronger.

This tank, in the V7.2 update, would exchange itself for the KV-1 and the KV-2. Technically, however, the KV itself has become the KV-1. The actual KV is no longer available from the in-game store.
