Unggoy Heavy

Gunner Grunt is a class of Grunt within the Covenant. Gunner Grunts are clad in green armor and operate Plasma Cannons and other fixed weapons used on the ground by the Covenant. Since they specialize in heavy weapons, they are seen in many places, with roles ranging from infantry to special operations. Gunner Grunts are a new addition seen only in Halo 2.

Combat
Gunner Grunts are usually seen in conjunction with other Covenant Infantry, and most often operate either a Fuel Rod Gun or a fixed Plasma Cannon. They usually will not flee from their position until the player is too close or out of range of their weapon, in which case they will pull out a Plasma Pistol and attack like a normal Grunt. They are easy to kill with any method you use.
