High Star Chieftain

, often abbreviated as HSC, is a suboordinate rank utilized by multiple Jiralhanae militaries, including the late New and Old Covenants, which merged into the Grand United Covenant; and the Confederate Jiralhanaean Emirates, among others. It was first invented by the shattered Covenant in 2560 to denote high ranking Jiralhanae capable of leading medium/large fleets and/or commanding large parts of their respective navy. When the Covenant split into its New and Old namesakes in the late 2570’s, both sides retained the new rank of High Star Chieftain along with many other ranks introduced simultaneously as said designation as part of the Second Covenant Mass Rearnament.
