Documented history

Expeditionary Firefighting and Rescue (EFR) Specialist

October 1, 2025 was the scheduled date for the active-component classification changes in the Marine Corps Total Force System, not a completion deadline for all Reserve retraining.

  • The available text does not specify the revised requirements.
  • Reserve retraining for Prior Service MOS Retraining Program, Active Reserve and Selected Marine Corps Reserve Marines was required as needed and subject to available funds. For Individual Mobilization Augmentees, Individual Ready Reservists and Standby Reservists, service-record entries instead relied on the headquarters conversion action appearing on the unit's Diary Feedback Report.
  • Formal schools were to continue awarding current MOSs until a MARADMIN directed implementation of the conversions.
Source extraction notes

New title: Aircraft Rescue and Fire Fighting (ARFF) Specialist. NAVMC 1200.1L (FY26) paragraph 4001.1b schedules the active-duty-component MCTFS batch for 2025-10-01. Paragraph 4001.6 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.
