O KV (em homenagem ao comissário de defesa Kliment Voroshilov) teve pelo menos duas torres com pequenas diferenças.
O primeiro tipo, com a placa frontal e escudo do canhão com reforços e a traseira em ângulo.
O segundo tipo, com a frente sem reforço e a traseira em uma única chapa.

PS: Há um relato de um KV, estacionado em um cruzamento de estrada, que parou uma divisão alemã até conseguirem trazer um 88.

"The next day, a single KV-2 heavy tank, at a crossroads in front of Raseiniai, managed to cut off elements of the 6th Panzer Division which had established bridgeheads on the Dubysa. It stalled the Division's advance for a full day while being attacked by a variety of antitank weapons, until it finally ran out of ammunition.[11][12][d][e]"
" The monster at the road.
On 23-24 June 1941 a single KV-2 of 2nd tank division conducted an armored road block in southern Lithuania (near Rassaynjay town), holding up the German advance. The Germans found themself in a trouble when they lost whole supply truck column. Numerious attacks including a battery of 50mm anti-tank guns (which were destroyed at 500m distance), Flak 88 (the Soviets allowed to mount this gun at 700m distance and then killed it) and an engineer unit attack all failed to silence the Russian tank. Artillery fire of 105mm howitzers achieved a hit to the track and the KV was partially immobilised. This heavy tank at the only road and surrounding swamps made German troops supply (with ammo, fuel and food) and wounded soldiers evacuation impossible. The Germans were forced to use such trick: 50(!) tanks immitated an attack, so it became possible to set another 88mm flak, which managed to eliminate the tank after two days it held up the advance of the entire 6th Panzer Division. The Stukas were not used because a commander not allowed an operation "against one tank". By the Germans' accounts, the crew could have escaped easily several times before the final attack, but the heroes always chooses own fate... "
