Hellhound

The Hellhound, based upon the Chimera chassis, is a flame tank. Its main weapon is the Inferno Cannon (in earlier versions called the "Dragon fire Thrower") which is a large flamethrower which projects streams of burning promethium at range, making the Hellhound well-suited to close-range support (such as countering enemy melee units that attempt to assault Imperial armour) and driving dug-in enemies out of cover. It is also armed with a Hull-mounted Heavy Bolter

The promethium storage is in the form of two large tanks, replacing the passenger area at the vehicle's rear. This makes the tanks, and the vehicle itself, vulnerable to enemy weapons.
