The Master Chief Petty Officer of the Starfleet (MCPOS, pronounced "mik-pos") is a unique non-commissioned rate of Starfleet, which has with it the paygrade of E-9. The holder of this rank and post is the most senior enlisted member of Starfleet, equivalent to the Sergeant Major of the Marine Corps, Master Chief Petty Officer of the Federation Naval Patrol, and Senior Enlisted Advisor to the Chairman of the Joint Chiefs of Staff of Starfleet.
S/He is appointed by the Chief of Staff of Starfleet to serve as a spokesman to address the issues of enlisted personnel to the highest positions in Starfleet. As such, he is the senior enlisted advisor to the Chief of Staff of Starfleet as well as the Chief of Fleet Operations. The exact duties vary, depending on the CoSS, though s/he generally devotes much of their time to traveling throughout the Federation observing training and talking to sailors and their families.
While the MCPOS is a non-commissioned officer, this billet is protocol equivalent to a Vice Admiral.
