The Chief of Staff for the Federation Starfleet (also known as the Starfleet Chief of Staff) was a senior Federation Starfleet flag officer, ranking below the Commanding Officer, Starfleet Command. In some matters, the Starfleet Chief of Staff possessed autonomy from their immediate superior; the office's authority over Free Agents was among those matters.
In the 2160s, there were five Joint Chiefs of Staff, representing the original five space fleets that made up the Federation Starfleet. The United Earth Space Probe Agency was responsible for exploration, the Andorian Imperial Guard specialized in the defense of the Federation's borders, the Tellar Space Administration handled operational support and supply, the Vulcan Space Council dealt with research and development and administration, and the Alpha Centauri Space Research Council provided research, funding, resources, logistical and administrative support.
