Wolverine The Wolverine is a United Nations Space Command ground-based anti-aircraft battery in Halo Wars designed to eliminate Banshees and other airborne Covenant units such as Spirit Dropships

Because the Wolverine has only been the subject of a few seconds of gameplay footage, and little explanation, it is presumed that they are used in an Air Defense Role, intercepting Covenant air support fighters to prevent bombing runs against UNSC ground forces and emplacements.
