Tropospheric Scatter Radio Multi-Channel Equipment Operator (NMOS)
1 October 2017 was the scheduled active-component batch-change date under paragraph 4001.1b, not a completion deadline. Paragraph 4002.2 instead prints 1 October 2008, a conflicting instruction; the 2017 date follows the FY18-specific implementation schedule.
- The available text does not spell out the revised requirements or explain the 0621 qualification in detail.
- 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 conversion action appearing on the unit's Diary Feedback Report.
- Formal schools continued awarding current MOSs until a MARADMIN directed implementation of the changes.
Source extraction notes
Source new title: Troposcatter Transmissions System Operator (NMOS)(0621). 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.
