The Destroid Monster is one of the heaviest piece of machinery ever built that is used by the RDF. It features four naval sized guns, 406 mm cannons, each able to fire 3 shells in its internal magazine. The Monster from the start was designed to be used as mobile artillery. Because of the Monster's extreme weight, its barrels are made out of extremely light material. The Monster is able to temporarly outgun a World War 2 battleship with its massive armament.
