Documented history

Signals Intelligence/Electronic Warfare Technician (PMOS)

1 October 2018 was the scheduled active-duty-component batch date in the Marine Corps Total Force System (MCTFS).

  • The specific revisions to the description and requirements are not detailed in this record.
  • Reserve retraining for PSMRP, Active Reserve and SMCR personnel was to be coordinated as needed for conversion, subject to available funds; service-record updates for Individual Mobilization Augmentees, Individual Ready Reservists and Standby Reservists used headquarters conversion action as authority.
  • Formal schools were to continue awarding current MOSs until a MARADMIN directed implementation.

Source new title: Signals Intelligence/Electronic Warfare/Cyberspace Operations Technician (PMOS). Figure 4-1 remarks: 2, 7. Paragraph 4001.1b schedules the active duty component MCTFS batch for 1 October 2018.

Signals Intelligence Analyst (NMOS)(2621, 2631, 267X)

MOS 2629 changed from Signals Intelligence Analyst, an NMOS associated with 2621, 2631 and 267X, to Signals Intelligence/Electronic Warfare Technician, a primary MOS (PMOS), while retaining code 2629. Its authorized grade range narrowed from corporal through master gunnery sergeant to staff sergeant through gunnery sergeant, with revised description and requirements.

Paragraph 4001.1b schedules 1 October 2017 as the active-duty-component Marine Corps Total Force System (MCTFS) batch date. Paragraph 4002.2 instead prints 1 October 2008, a conflicting date; the 2017 date follows the FY18 edition's explicit implementation schedule.

  • The conversion table flags description and requirement changes but does not explain their details.
  • 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 were separately authorized by the headquarters-origin conversion action on the unit's Diary Feedback Report.
  • Formal schools were to continue awarding current MOSs until a MARADMIN directed implementation of the conversions.
Source extraction notes

Source new title: Signals Intelligence/Electronic Warfare Technician (PMOS). Figure 4-1 remarks: 2, 4, 7, 8. Encoded as renamed because the allowed output vocabulary has no status-change value and the source also changes the title/status of the same code. 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. The conversion table changes the classification's grade range from Cpl-MGySgt to SSgt-GySgt. These ranges are not a direction to promote or demote individual Marines.
