Heretic Sangheili Major

Heretic Elite Majors are denoted by their golden armor. They serve as commanders to the Minors and the Heretic Grunts. They also guard places as designated by the Heretics leader, Sesa 'Refumee. It's very likely that the Majors remained inside of the facility they used as a base, patrolling the long and dark hallways of the Threshold Gas Mine on foot, while numerous Minors patrolled the outside by way of Heretic Banshee, making the mine almost solid in defense.

They are fearless warriors that ensured that their jobs are done well. They were enemies in the levels The Arbiter and The Oracle. However, the Prophets sent in squads of Special Operations Elites and Grunts, accompanied by the Arbiter, to quell the heresy and the group infiltrated the mine and completed their objective. Most of, if not all, the Majors were killed when the gas mine fell into the depths of Threshold, after the Arbiter cut the cables holding the mine up.
