Electromagnetic Spectrum Management Chief
Paragraph 4001.1b schedules the active-component system conversion for October 1, 2026. This is the scheduled batch-change date, not a retraining completion deadline.
- Reserve retraining for Prior Service MOS Retraining Program, Active Reserve and Selected Marine Corps Reserve Marines is required as needed and subject to available funds; entries for Individual Mobilization Augmentees, Individual Ready Reservists and Standby Reservists instead use the headquarters conversion action shown on the unit's Diary Feedback Report as authority.
- Formal schools and training detachments continue awarding current MOSs until a MARADMIN directs implementation of the conversions.
Source extraction notes
Renamed Electromagnetic Spectrum Maneuver Chief and changes NMOS to PMOS. Encoded as renamed because the allowed output vocabulary has no status-change value and the source also changes the title/status of the same code. NAVMC 1200.1M (FY27) paragraph 4001.1b schedules the active-duty-component MCTFS batch for 2026-10-01. Paragraph 4001.5 separately addresses Reserve retraining, subject to available funds for the specified groups, and records for Individual Mobilization Augmentees, Individual Ready Reservists and Standby Reservists. Paragraph 4002.3 keeps formal-school MOS awards unchanged until MARADMIN implementation direction. The scheduled batch date is not proof of an individual's qualification, retraining or record-update completion.
