Notification of 1721 PMOS Transition

1.  Background:  The Deputy Commandant for Information (DC I) established a Cyber Occupational Field (OccFld) Operational Planning Team to evaluate the force generation process and the challenges associated with creating a professional cyber workforce.  The end state is to produce a ready force to meet emerging technologies, support emerging command and control requirements, adapt to rapid changes in technology, and enable operations within a dynamic information environment.  The working group realigned skillsets and Military Occupational Specialty (MOS) structure to streamline the force generation process and improve the sustainability of the cyberspace workforce.  The new MOS structure will be updated in the FY22 Tables of Organization (TO) and Authorized Strength Report (ASR) in accordance with Reference (a) and updates will be reflected in Reference (b).  The OPT outcomes are outlined in Reference (c) and are approved for implementation by the Doctrine, Organization, Training, Materiel, Leadership and Education, Personnel, Facilities, and Cost (DOTMLPF-C) Working Group.  The MOS Manual Updates intended that accompany this initiative were published in Reference (d) and will be updated during the next planned update of Reference (b).
