Sangheili Majors, also referred to as Sangheili Officers, are members of the Covenant military and are also higher in rank than Minors.

They are medium-low in the Covenant ranking structure. Only Majors can take on Ossoona temporary assignments, mainly due to the fact that seasoned warriors prefer combat, not stealth, and Minors are too inexperienced. Majors often command groups of Minors as well as lesser races in ground combat situations. In addition to commanding ground troops, Majors can also take on the role as "second master" which allows them to become a Sangheili Shipmasters second in command of their ship. Majors have much strengthened overshields than Minors and are capable of surviving an entire squad of UNSC Marines, also they appear to be equivalent to UNSC Lieutenants.
