Designed by M&M Industries to assault fortified positions or vehicles with kinetic barriers the mobile siege guns each carry a single huge front mounted cannon.
Nicknamed the 'Tank Destroyer' it is unable to track its targets since it lacks a traverse turret but against its usual target of a stationary structure this is rarely a problem. The cannons are primed with high calibre armour piercing rounds, each containing a large amount of explosive. Designed to swarm fortifications and blast holes in them for the Legions to exploit, they have been exceptional in that role. They are a perfect low cost alternative to the newly designed, massive MCAS vehicles.
