Hello, the flamethrower in the KV-8 or T-55 tanks are too weak, realistically the flamethrower should destroy the enemy tank, the engine should be on fire, read some history books
It’s a gimmick feature that is only true effective against open-top vehicles, it won’t destroy vehicles although engine damage could be considered. Flamethrower falls under the grenade launcher situation: It exist, it works in-game but doesn’t mean it’s useful for the most part.
Have you read such a history book yourself?
Because it was only effective on certain tanks with a certain design of engine air intake. Certain tanks with different designed engine decls had no issues.
