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. However, even these higher-ranked Grunts hold no power over any other forces in Covenant society.

They wear crimson armor as opposed to the orange armor of Minor Grunts and sometimes, are more courageous than Minor Grunts, sometimes not fleeing the battle scene. If all the surrounding Elites are killed, sometimes they will stand and fight.

Appearances
Major Grunts often appear leading several Minors into combat, but they sometimes appear by themselves. The first Major you'll see in Halo: Combat Evolved is right after you get your M6D Pistol in the Pillar of Autumn level. In Halo 2 it's most likely during your fight in Hangar A-01. In Halo: CE and Halo 2, they will almost completely replace Minor Grunts on higher difficulty levels. This can be quite the pain in the neck, as they are much tougher.

Deployment
Major Grunts are deployed with all other types of Grunt. Mostly Minors. In the Games, they are usually the first one to jump out of the Dropships.
