Heretic Grunts mainly wield Needlers, and never wield Plasma Pistols unlike their Covenant counterparts. They can also man Plasma Turrets and wield Fuel Rod Guns as heavy weaponry. Unlike Covenant Grunts, Heretic Grunts are well more respected by the Heretics. They are far more dangerous then Covenant Grunts as they do not panic and ran away when their Heretic Elite commander is killed, but they do not suicidal attack enemy forces.
