Magna-melta

A Magna-Melta is a heavy, vehicle-mounted, short-ranged, area-effect heat cannon. Magna-meltas were originally designed for space assault craft like te Caestus Assault Ram to enable them to turn a large cubic volume of starship hull-plating into liquid slag.

A Melta Weapon of this magnitude's effects on less durable targets such as main battle tanks and living matter are simply catastrophic. The aptitude for use of this powerful weapon was not lost on the Tech-priests of Mars, who soon began mounting the Magna-Melta upon the turrets of Deimos Infernus Predators. This ancient pattern of Predator has now largely been replaced by the Land Raider Redeemer in many Space Marine Chapters.
