Cerberus

The Cerberus Heavy Tank Destroyer is a super-heavy tank destroyer that was used in limited numbers by the Space Marine Legions during the Great Crusade and later during the Horus Heresy of the late 30th and early 31st Millennia. The Cerberus was a rare and experimental variant of the super-heavy Spartan Assault Tank also used by the Space Marine Legions, both of which made use of the same hull, armour, and chassis design.
