- These warriors find their minds filled with an all-consuming impulse to kill and kill again, to ensure that the jaws of the Death Wolf could feast upon the enemies of Mankind with proper reverence.

- Powerful Heavy Infantry that are devastating in melee combat and are equipped with Yimira Class Stasis Bombs.
