The KV-2 (Patreon)

The massive, heavily armoured turret of the KV-2 made it one of the most distinctive tanks ever built and one of the most formidable vehicles on the battlefield in 1941. However it wasn’t originally designed as a tank. Armed with a 152mm M-10T howitzer, it was intended for use against fortifications. Only 334 were built, and production ended in October 1941 as Soviet tank factories were moved east in the face of the German invasion.
