During the Republic campaign to secure Umbara, the natives of the shadowy world unleashed all manner of previously unseen advanced technology against the clone trooper forces. The Umbaran MHC -- mobile heavy cannon -- is a titanic juggernaut built atop six powerful, ground-shaking legs. The dome-shaped body of the spider-like tank is heavily armored, able to withstand anti-armor infantry rockets. Mounted atop the dome on an articulated arm is a powerful electromagnetic plasma cannon. The monstrous MHC has almost no weaknesses.
