KV-8 firing

An artist's impression of a KV-8.

The KV-8 was a Soviet flamethrower tank based on the KV-1. Next to the flamethrower (an ATO-41) is a machine gun (M1932) made to look bigger than it is. There were two upgrades for the KV-8, the KV-8S which had a better flamethrower (ATO-42) and the KV-8M which had two flamethrowers. Only two KV-8M's were made.
