Documented history

Small Unmanned Aircraft System Specialist

1 October 2025 was the scheduled active-component Marine Corps Total Force System batch-change date.

  • The specific requirement changes are not described in the available text.
  • 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 relied on the headquarters-origin conversion action shown on the unit's Diary Feedback Report.
  • Formal schools were to continue awarding current MOSs until a MARADMIN directed implementation of the conversions.
