Ares MTB

In the late 1970s, the Pacific Car and Foundry company developed a project for a medium tank with a smoothbore gun. The vehicle was supposed to develop into a main battle tank with a new armament set, as well as enhanced detection and aiming systems. A 75 mm or 85 mm gun was considered for the primary weapon. The vehicle was small but fairly heavy. The project was deemed overly complicated due to its huge two-ton engine, relatively weak armament, and the inclusion of dual drive for the outer and inner tracks. The work was stopped before a prototype was built.
