Tracked Enforcer gun carriers used to defend the Megakat Nuclear Plant from Volcanus. However, they were no match for the giant demon and were destroyed by his fire breath. Later, the halftracks were used against Zed in an effort to prevent him from acquiring the Mega-Beam, but they failed. When Zed was destroyed and fell apart, the Enforcers abandoned their vehicles, and the halftracks were presumably destroyed by the falling pieces of the giant robot.
