The Ion Plasma Tank is a vehicle appearing exclusively in Unreal Tournament 2004's Glacier. Unlike most one-appearance vehicles, Ion Plasma Tanks are used exclusively by the Attackers. Often compared to the Leviathan and Ion Cannon due to their similar attacks, health, and rarity, the Ion Plasma Tank is the fastest of the three with the fastest shooting time, but has the lowest health and weakest main gun of the three (it takes as many as 8 shots to kill an idle Leviathan; however, a Leviathan takes 2 shots, and the Ion Cannon takes 3).
