Karacnos Assault Tank: Mechanicum

By taking the venerable Triaros Armoured Conveyor chassis and filling its hold with mortar tubes, the Mechanicum created one of the most effective and resilient artillery tanks of the Heresy – the Karacnos Assault Tank. Well protected on all sides and armed with sponson-mounted lightning locks, the lingering radiological flames its ordnance leaves behind are lethal to both fleshy troopers and armoured assailants alike.
