Documented history

Critical Skills Operator

1 October 2025 is the scheduled date for the active-component personnel-system batch change.

  • The specific description and requirement changes are not detailed in the available evidence.
  • Reserve retraining for Prior Service MOS Retraining Program, Active Reserve and Selected Marine Corps Reserve Marines is required as applicable and subject to available funds. For Individual Mobilization Augmentees, Individual Ready Reservists and Standby Reservists, service-record entries instead use the headquarters-origin conversion action on the unit's Diary Feedback Report as authority.
  • Formal schools continue awarding current MOSs until a MARADMIN directs implementation of the conversions.
Source extraction notes

New title: Marine Raider (PMOS). 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.
