Thel 'Vadamee in a unique helmet and cloak. Within the Covenant's successor factions, the warlord Jul 'Mdama has adopted the title of Supreme Commander - though this title is sometimes used interchangeably with the title of 'Supreme Leader'. These officials were often the only officials within the fleet with authority capable of challenging the Supreme Commander's decrees. To assist in their duties, Covenant fleets often assigned a Precentor - a San'Shyuum official tasked with reporting directly to High Charity and serving as a mediator for the Supreme Commander among other duties. The political machinations of the Supreme Commander allowed them to outfit and service their own ships, and they served as the sole senior officer to a Field Marshal. As such, they held extremely large amounts of power and independence - even moreso than their United Nations Space Command counterparts. Within these formations, the word of the Supreme Commander was law, and only the actions of their sponsoring ministry, the High Council, or the Hierarchs themselves could countermand their orders. Within a given armada, a Supreme Commander served as the lead fleetmaster among the several present, with each subordinate fleetmaster tasked with maintaining their own fleet forces.
