Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Surveying and Mapping Technicians

Integrating battlefield sensor information and maneuver control measures provides a foundation for organizing geographic information in map overlays.

How to prepare: Complete a hands-on GIS course and build an overlay-map project that demonstrates layer checks and error corrections.

What the civilian work involves
  • Check all layers of maps to ensure accuracy, identifying and marking errors and making corrections.
  • Produce or update overlay maps to show information boundaries, water locations, or topographic features on various base maps or at different scales.
Civilian tools and software (examples)
  • ESRI ArcGIS software

Network and Computer Systems Administrators

Operating networked battle-command systems and maintaining automated equipment provides a starting point for learning civilian computer-system troubleshooting and administration.

How to prepare: Build a Linux lab to practice network configuration, backups, and recovery from system faults. Verified 13J duties establish operator and unit-level maintenance, not enterprise network administration experience.

What the civilian work involves
  • Maintain and administer computer networks and related computing environments, including computer hardware, systems software, applications software, and all configurations.
  • Perform data backups and disaster recovery operations.
  • Diagnose, troubleshoot, and resolve hardware, software, or other network and system problems, and replace defective components when necessary.
Civilian tools and software (examples)
  • Linux
  • Microsoft Active Directory
