MCA BUREAU (PERS-453)
Manning Control Authorities (MCAs) are responsible for the continuous management of authorized priority manning that is necessary to ensure mission accomplishment and to provide the order of importance for which activities will be priority manned. All activities are assigned to one of two MCA's - Fleet and Bureau:
MCAF sets the Navy Manning Plan (NMP) for all sea and fleet operational commands, as well as all shore duty activities that directly support operational readiness.
MCAB is responsible for the manning and placement functions for all other shore duty activities relating to infrastructure, training, recruiting, and joint commands. Manning is the function of determining the quality, quantity, and priority for assignment of personnel to all billets within a composite. Placement is the function of communicating unit personnel vacancies to the assignment control authorities and directing the order in which these vacancies are to be filled.
MCAB is responsible for 38 Budget Submission Offices (BSO), which are the primary agents for determining shore manpower requirements. MCAB manages NMP and sets priorities for over 4,200 Naval Activities, encompassing more than 41,000 billets.
