Super Heavy Spank (High mobility armor meme.)

It spanks and its as fast as mechanized, its reliability isn't the highest but the point is to have the most armor that can fit in a support company that matches early mechanized in speed. The enemy will be penetrated by this gun, and its fast so it spanks. What more could you ask for a tank (Don't look at the fuel economy don't look at the range.) ITS FOR PAPAL BATHTUB WARFARE OK. HE GETS THE FIST OF GOD AND WE WILL EVOLVE THIS INTO GODS KNUCKLES TO SEND THE MESSAGE.
