Notification of Fiscal Year 2024 Merger of Primary Military Occupational Specialty (PMOS) 1142 and 1161

1.  Per reference (A), the 11XX community supports the merging of these two Primary Military Occupational Specialties (PMOS).  The Engineer Equipment Electrical System Technician (1142) and Refrigeration and Air Conditioning Technician (1161) will merge into a single MOS, Utilities Systems Technician, creating the MOS designator 1164.  Combining these fields results in a multidisciplined, highly skilled Marine that enhances self-support provided to commanders and optimizes logistical support in austere environments.  The 1142 and 1161 PMOS fields have complimentary and overlapping skillsets that meet the Commandant's intent to create opportunities for "Marines that can do more," while enabling the service to retain talent IAW reference (B).

4.  M&RA (MMIB) will report unit diary entries to convert active component Marines with PMOS 1142 or 1161 to PMOS 1164.  These Marines will be identified in a reclassification spreadsheet provided by the (11XX) Occupational Field Sponsor to MMIB.  Reserve Affairs Management will convert reserve component Marines with PMOS 1142 or 1161 to PMOS 1164.  No action is required by the individual Marine.
