GENTEXT/REMARKS/1. Each year the Marine Corps Human Resource Development Process is synchronized through publication of reference(ref) (a), the Military Occupational Specialty (MOS) Manual. Ref (b) governs the process. The manual defines occupational specialties found on tables of organization, identifies skills of Marines to meet organizational requirements, and otherwise provides information that enables the Marine Corps to carry out its assigned mission to organize, train, assign, and manage the force. The annual revision of the MOS Manual was coordinated with the February authorized strength report.
2. The Fiscal Year (FY) 2021 MOS Manual contains significant and numerous changes. A complete list of changes can be found in the conversion tables (chapters 2 and 4) of ref (a), which can be viewed on the website identified in paragraph 4 below.
2.A. New officer MOSs were created in occupational fields (OccFld) 02, 05, 09, 60, and 65; and enlisted MOSs were created in OccFlds 08, 09, 27, 31, 45, 57, 60, 61, 65, and 80.

3. The Deputy Commandant (DC), Combat Development and Integration front-end analysis process for developing individual training standards continues to be used to affect the restructure of OccFlds based upon validated current Marine Corps needs. To ensure content accuracy and completeness, the MOS Manual entries were reviewed by MOS sponsors, Total Force Structure Division, Training and Education Command, and Manpower and Reserve Affairs (M&RA).
