NotesThe KV-1 (Kliment Voroshilov) heavy tank came as a major surprise to the Germans as their standard 37mm anti-tank guns simply bounced off its thick armour. In 1941 it was the best heavy tank in the world and used by the Soviets as a break through tank against prepared defences. It had a combination of heavy armour and powerful gun plus the ability to cross bad terrain, but had poor crew visibility and was slow. It caused upheaval when it was encountered and the only real defense against it was from the 88mm Flak gun. Its slow speed was its down fall and it could not keep pace with the T-34, this and the improvement in German anti-tanks weapons made it less effective and it was gradually phased out to make way for the IS series of heavy tanks.
