Documented history

European Cryptologic Linguist (PMOS)

1 October 2017 was the scheduled active-component MOS batch-conversion date under paragraph 4001.1b. Paragraph 4002.2 instead prints 1 October 2008 for the batch change, a conflicting instruction; the 2017 date follows the FY18-specific schedule.

  • 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; entries for Individual Mobilization Augmentees, Individual Ready Reservists and Standby Reservists were authorized separately by the Headquarters-origin conversion action on the unit's Diary Feedback Report.
  • Formal schools and training detachments were to continue awarding current MOSs until a MARADMIN directed implementation of the conversions.
Source extraction notes

Figure 4-1 remarks: 3. 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.
