The Storm Unit (Or Sturm Unit, as it was known in the Japanese release) was the first armor unit produced for the Berserk Fury. This is the only Berserk Fury CAS design to have been released as an actual model kit. It is a melee-oriented version of the Berserk Fury, sporting two X-Breakers as its primary weaponry, as well as sporting a drastically increased top speed and improved armor.
