Behemoth

Heavy Unit #5: The Behemoth
If the other tanks didn't scare you, the Behemoth certainly will. Fuelled only by potato peels, this is the most environmentally friendly tank available (with the tiny exception of the destruction it causes when fired).

The most powerful tank on the battlefield may be slower than a tortoise, but if you're in range of its triple barrel, you'll see that white light at the end of a tunnel everyone talks about. 💣⚰️
