Documented history

Heavy Ordnance Vehicle Repairer/Technician

October 1, 2026 is the scheduled active-component batch conversion date under paragraph 4001.1b, rather than a separately stated effective date for MOS 2146.

  • 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 use the headquarters-origin conversion action on the unit's Diary Feedback Report as authority.
  • Formal schools and training detachments continue awarding current MOSs until a MARADMIN directs implementation.
Source extraction notes

Deleted MOS; no successor named. 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.
