The MPCU is the top of the line unit for close quarters combat, riot control, suppressing rebellions, holding chokepoints, and defending. The unit is defined as the "Exo-Skeleton" and pilot wearing it, making it able to carry much heavier loads than a usual person can, making it able to carry large shields and many shoulder mounted weapons without breaking a bone because of recoil and weight. This also makes them well suited for riot control, as shields and larger shotguns and flame throwers can be held with ease and more maneuverability. Notably, the generic MPCU is often armed with a modified or unmodified Old Earth KS-23's, 4 gauge caliber shotguns able to go through most crowds of enemies. However, the legs are often listed as stilts, as they're often seen as mobility scooter versions of glorified mechanical metal stilts.
Heavy inspiration from the Roblox game "Dummies VS Noobs"'s enemy, the APU. KS-23 is a Russian, or Soviet, designed shotgun, made to fire anti aircraft rounds that got turned into shotgun rounds. Not the best piece of art to come out of the slums called my backlog of art projects.
