Known formally as Metal Gear Gustav, Mass Production Model. Developed in 1999 by Dr. Pettrovich Madnar in Zanzibarland. The nuclear module has been removed to reduce the unit's weight. It features an enhanced sensor package, making it suitable for localized conflicts where regular tanks are useless. A single unit is deployed with each infantry company to act as the company's eyes and ears and provide backup to the infantry. It was intended to be deployed in Zanzibarland but never actually saw combat.
