GENTEXT/REMARKS/1.  Each year the Marine Corps Human Resource Development Process is synchronized through publication of reference (ref) (A), the Military Occupational Specialties (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 2023 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 (par) 4 below.
2.a.  New officer MOSs were created in occupational fields (OccFld) 09, 17, and 66; and enlisted MOSs were created in OccFlds 08, 09, 17, 61, and 88.
2.b.  Enlisted MOSs 1711 and 3112 have been deleted.
2.c.  There are grade structure changes in officer OccFld 48; and there are grade structure changes in enlisted OccFld 73.
2.d.  There are many changes to the summary, requirements, and prerequisites fields within the MOS Manual in officer and enlisted OccFlds 01, 02, 03, 04, 05, 06, 08, 09, 13, 17, 18, 26, 28, 30 31, 33, 34, 35, 45, 48, 55, 57, 58, 59, 60, 61, 62, 63, 65, 66, 70, 72, 73, 75, 80, and 88.

3.  The Deputy Commandant (DC) Combat Development and Integration front-end analysis process is no longer conducted as a stand-alone process.  Front-end analyses have been incorporated into Phase 0 of Training and Readiness Manual updates.  To ensure content accuracy and completeness of the MOS Manual, the MOS Manual entries were reviewed by MOS sponsors, Total Force Structure Division, Training and Education Command, and Manpower and Reserve Affairs (M&RA).
