Documented history

Military Police Law Enforcement Advisor (MPLEA) (NMOS)

1 October 2017 was the scheduled active-component MOS batch-change date under paragraph 4001.1b. Paragraph 4002.2 instead prints 1 October 2008, a conflicting date; the FY18 implementation schedule supports using 1 October 2017.

  • The available record does not specify the description or requirement changes beyond the new title.
  • 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.
Source extraction notes

Source new title: Military Police Investigator (MPI) (NMOS)(5811). Figure 4-1 remarks: 2, 7. NAVMC 1200.1C (FY18) paragraph 4001.1b schedules the active-duty-component MCTFS batch for 2017-10-01. 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. Paragraph 4002.2 prints 1 October 2008, in conflict with the 1 October 2017 schedule in paragraph 4001.1b. The recorded date follows the edition-specific schedule in paragraph 4001.1b; the conflicting printed instruction is not silently corrected.
