Unggoy Major

Major is a Covenant Grunt rank. Only one step higher than Minor Grunts in rank, these Grunts are slightly more powerful than their lesser counterparts. They often lead Grunt Minors in battle, and sometimes entire Lances when no Elite is present or alive. However, even with increased rank, Grunts of any kind hold no power over any other forces in Covenant society.

Combat
Major Grunts usually wield Plasma Pistols and Needlers, but occasionally one will carry a Fuel Rod Gun in later stages of the games. They are far more experienced than Minors, therefore a higher priorty. Especially on higher difficulties, they throw grenades very frequently. In Halo 2, though, they're much quieter.Major Grunts are slightly harder to kill, but it is still effective to either melee attack them from behind or kill them with a headshot using a Pistol or a Battle rifle

Appearances
Major Grunts often appear leading several Minors into combat, but they sometimes appear by themselves. The first Major you'll see in Halo 1 is right after you get your M6D. In Halo 2 it's most likely during your fight in Hangar A-01.
