Overview The High-Explosive-Armor-Piercing-Ordinance-Firing Super Heavy Intelligent Tank (H.E.A.P.O.F.S.H.I.T) is the most formidable vehicle in the universe. It can run over a Grunt and fly like a Banshee (if the sped up on a decently steep ramp). After the Human-Covenant War, the UNSC let them loose and they could roam free in the Gobi desert ever after and lived happily until the end of the little green and blue ball.
