Sub-commander

Sub-commander was a military rank within the armed forces of the Covenant. For most of its history, the title was almost exclusively held by Sangheili.

Overview
Sub-commanders are subordinate to Commanders; together, these roles allowed the Sangheili to maintain unit cohesion across the Covenant's various client species. The rank was employed by Covenant Special Operations, with SpecOps personnel serving in the sub-commander role donning a Sangheili harness in dark blue-green colouration.

Sub-commander Bero 'Kusovai is the only known Sangheili to have held the title; a position in which he served inside SpecOps until his death in the Battle of Installation 04.
