Communications-Computer Systems Planning and Implementation
The specialty covered base communications-computer planning, project implementation, system integration, and contract management.
The crosswalk lists 3C3X1 from October 1993 through April 2010 and begins 3D1X1 in August 2009, without exact days. These overlapping windows are distinct from the broader cyberspace-support transition effective November 1, 2009.
Source extraction notes
3C3X1 covered communications-computer planning, requirements, project implementation, architecture, configuration, integration and service contracts. Its DMDC skill-level validity windows run from October 1993 through April 2010, without day precision. The broader 3DXXX transition began 1 November 2009, while 3D1X1 crosswalk entries begin in August 2009. This record carries 3D1X1 as a functional relationship, not proof that every 3C3X1 Airman received that personnel conversion. Primary and alternate paths were described in the Air Force announcement.
