The Scarak Tanks are the super majors of the Scarak Hive.
The Scarak Tank is part of the Scarak family. The Scarak race consists of bug-like creatures that dominate the howling sands. They used to enslave the Feran's and use them for manual labor, which is why they have the freedom bracers around their ankles.
They come in various forms such as workers, locusts, tanks, and most importantly, the broodmother. Scarak's are hatched from Scarak egg sacks.
