Intelligence Technology and Data Chief

1 October 2025 is the scheduled active-component Marine Corps Total Force System batch-change date under paragraph 4001.1b, not a retraining completion deadline.

  • The specific description and requirement changes are not detailed in the available material.
  • Reserve retraining for Prior Service MOS Retraining Program, Active Reserve and Selected Marine Corps Reserve Marines was required as applicable and subject to available funds. For Individual Mobilization Augmentees, Individual Ready Reservists and Standby Reservists, service-record entries were authorized by the headquarters-origin conversion action on the unit's Diary Feedback Report.
  • Formal schools were to continue awarding current MOSs until MARADMIN direction implemented the changes.
