A Harvester Cannon is a large, multi-barrelled, rapid-firing weapon that is wielded by Soul Grinder Daemon Engines. The Soul Grinder is usually armed with a single Harvester Cannon on one arm, used in conjunction with an Iron Claw close combat weapon located on its other arm.
The weapon is attached to the daemon's wrist, on its right arm and can be used with an organic pincer version of the Iron Claw that it wields on its other arm or with a daemonic Warpsword. The Harvester Cannon is capable of firing large calibre solid shells that are effective against infantry and light vehicles and can also fire specialised flak shells to engage enemy aircraft.
