3d Anaglyph of a Soviet World War Two KV1 Battle Tank
KV1 Heavy Tank
The KV-1 was the main Soviet heavy tank. Its thick armour was able to withstand the rounds from the short 75 mm 37 mm guns of the early Pz IV and Pz III.
It was armed with the same 76 mm gun as the T34 but had thicker armour and was slower.
