The Guntank is the third variety of prototype
mobile suit
developed by the
Earth Federation.
Lacking legs and hands, this crude mobile suit is relatively immobile and can't defend itself in close-range combat, and is thus used mostly for long-range artillery fire. The Guntank is initially manned by driver
Ryu Jose
and gunner
Hayato Kobayashi,
and is later modified so that Hayato can operate it single-handedly from the head cockpit.
