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.

Telecommunications Equipment Installers and Repairers, Except Line Installers

Fault isolation, alignment, and corrective maintenance on digital radios and tactical data link equipment transfer directly to troubleshooting telecommunications equipment.

How to prepare: Complete a hands-on telecommunications equipment lab that covers circuit testing, fault isolation, and verification of repaired equipment against specifications.

What the civilian work involves
  • Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools.
  • Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation.
  • Assemble and install communication equipment such as data and telephone communication lines, wiring, switching equipment, wiring frames, power apparatus, computer systems, and networks.
Civilian tools and software (examples)
  • Cisco IOS

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Detecting and isolating faults and performing corrective maintenance on data link and command and control systems provide a foundation for diagnosing commercial and industrial electronics.

How to prepare: Take a practical industrial electronics troubleshooting course focused on testing unfamiliar equipment and documenting diagnosis and repair 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.
