The guidance herein describes the Marine Corps Occupational System. The Commanding General, Training and Education Command (CG, TECOM) acts in concert with the Deputy Commandant (DC), Manpower and Reserve Affairs(M&RA) and the DC, Combat Development and Integration to support the Commandant of the Marine Corps (CMC) in his responsibilities to staff the billets found in the T/O and to train those filling the billets. CG, TECOM acts as the principal adviser to the CMC for all training and education matters, reporting directly to CMC as a supporting activity commander within the Supporting Establishment. Organizational requirements are set forth in the T/O and are tabulated with number codes derived from the Marine Corps Occupational System described in this Manual. The codes define the different individual skills required by Marine Corps organizations. The same codes are used by the DC, M&RA to develop and maintain a personnel inventory of skilled Marines for assignment to meet the manning requirements for the organizations. The occupational system by necessity must be somewhat rigid in its process and categorization to maintain accuracy of the meaning of the number codes. To maintain flexibility, the Military Occupational Specialties (short title: MOS manual) will be reviewed and revised on a routine basis annually, or more frequently in extraordinary circumstances, using the procedures outlined in this document. Organization of the MOS Manual and determination of the MOS codes to be assigned rest with the CG, TECOM.
a. Highlights of MOS Manual update considerations included in thisprogram guidance are as follows:
(1) Specific guidance in the form of checklists for submitting changes to existing MOSs or for creating new MOSs.
(2) Procedures for adjudicating disputes that arise among stakeholders (the occupational field, TECOM, M&RA, Marine Corps Recruiting Command, Training Command and Total Force Structure Division) when there is not consensus on proposed changes to the MOS Manual.
(3) The division of responsibilities among stakeholders for review and concurrence for submitted changes to the MOS Manual.
