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.

Network and Computer Systems Administrators

Configuring, monitoring, integrating, and troubleshooting multi-user intelligence systems and networks transfers directly to maintaining civilian computing environments.

How to prepare: Build a small Linux or Microsoft Active Directory lab and document system configuration, a backup-and-restore test, and resolution of a simulated network fault.

What the civilian work involves
  • Maintain and administer computer networks and related computing environments, including computer hardware, systems software, applications software, and all configurations.
  • Diagnose, troubleshoot, and resolve hardware, software, or other network and system problems, and replace defective components when necessary.
  • Operate master consoles to monitor the performance of computer systems and networks and to coordinate computer network access and use.
Civilian tools and software (examples)
  • Linux
  • Microsoft Active Directory
  • Bash

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Field and sustainment maintenance of intelligence equipment, peripherals, and associated devices provides a foundation for diagnosing and repairing commercial electronic equipment.

How to prepare: Complete a supervised electronics troubleshooting lab focused on commercial equipment, recording fault diagnosis, repair actions, and post-repair test results.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
  • Install repaired equipment in various settings, such as industrial or military establishments.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS
