Grunt (Halo 3, green)
At 3¾ inches tall, the Grunt is a menace to the human race, and represents the vast majority of the Covenant infantry. The Grunts are the lowest tier of the Covenant hierarchy, and move in packs. They are expected to unquestioningly obey the commands of their Brute commanders. Outfitted with weapons including the Plasma Pistol and Needler, the Grunts may not seem much more than cannon fodder, but in groups, they can be deadly.
