The Starfleet Commander-in-Chief is the highest ranking Starfleet officer, responsible to the President for the implementation of all command and policy directives to the Starfleet. The Commander-in-Chief is seen as the uniformed Starfleet equivalent to the Secretary of the Starfleet, and is not a subordinate.
Operational control of Starfleet forces is overseen by the Commander Starfleet, who receives administrative tasking from the Secretary of the Starfleet and operational directives from the Commander in Chief. Implementing the various commands, directives, and policies into a single functioning entity is the responsible of Starfleet Command, considered a “hub” for the Secretary of the Starfleet, Commander-in-Chief, and the Commander Starfleet.
