The KV-13 is a Tier VII Soviet Medium Tank.
This tank is faster than the KV-1S, with its hull armor being equal to that of KV-3 and IS. This tank's speed can be deceiving and can only reach decent top speed while going downhill. The gun has a relatively fast rate of fire, but lacks penetration of other medium tanks. It can sidescrape like other KV tanks but it’s armor is slightly weaker though still strong and its mobility a lot higher. Play it carefully, and you’ll win the battle. It has a decent size profile but it does have low hp and a bad gun.
It's strengths include effective armor, decent maneuverability and high rate of fire.
It's weaknesses include low damage and penetration and low engine power.
