Cyberspace Network Management Technicians (MOS 255n)

We had to address the question What is a warrant officer MOS in the process of repurposing our current MOS. Branch officers have areas of concentration and enlisted Soldiers have MOSs. Warrant officers have both. A warrant officer MOS is comprised of a two-digit branch identifier e.g., 25 for Signal, a third digit to define an AOC e.g., 255 for Network Operations, and a fourth alpha character to finally comprise a warrant officer MOS e.g., 255N for Cyberspace Network Management Technician. The MOS 250N was created in 1998 and subsumed MOS 250A and 250B in April 1999. It then remained relatively stable until September 2000 when all COMSEC functions were transferred to newly created MOS 254A and all CW5 positions were transferred to newly created MOS 255Z. Since then, no major changes have taken place other than the inclusion of newer transport and routing technologies.
