Technical and Historical Notes

When the Dianna Counter forces arrived on Earth to begin colonization, they brought a variety of mobile suits with them, including the MRC-F20 SUMO. One of the most famous during the conflict was the gold colored one piloted by Royal Guard captain Harry Ord. The standard model, however, came in a white-silver color. As the acronym implied, the SUMO was meant for maneuvering. It was short and light weight, much like the Earth Militia's SYSTEM ∀-99 (WD-M01) ∀ Gundam. In fact, both the SUMO and the Turn A shared the same pelvis cockpit system. When Loran Cehack abandoned the Turn A with his Core Fighter, Gym Ghingnham had a SUMO cockpit retrofitted onto the Turn A for use by his own forces.

Though the SUMO was designed mainly for use in space or on the Moon, it was quite versatile on Earth as well. The addition of a skirt-like flight booster allowed extended flight or flight high in the Earth's atmosphere. The SUMO's armament consisted mainly of a powerful hand beam gun, as well as a heat fan that served as a melee weapon. Another weapon in the SUMO's arsenal was the IF generator, a device that allowed the SUMO to create an I-field. When several SUMO units used their IF generators together, it could create a powerful force field to hold another suit in place.
