The Motorized Battle Tank (or MOBAT) was one of the first vehicle playsets created for the 3 3/4" line of G.I.Joe figures. The vehicle was battery-powered or 'motorized'.
This playset came with 'Steeler', accesories, and blueprints. There are two versions of this that exist: one with straight-arm figure from 1982, and one with "swivel-arm", released in 1983.
