This is a posable, high-grade or better injection-plastic kit of an item from the Gundam universe.
The Guntank from "Gundam The Origin" is more squat and vehicle-like than we're used to seeing. It has movable arms and waist, elevating cannons (with dampers that move with the angle of the turret), and flexible (although non-working) treads. Includes details such as radiator fins and a tank hatch that can be built in an open position. Molded in gray, dark gray, and khaki, with dry-transfer decals for markings.
