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.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Experience using test equipment and diagnostic programs to isolate faults, align equipment, and restore electronic systems transfers directly to commercial electronics repair.

How to prepare: Complete a hands-on troubleshooting exercise on commercial or industrial electronic equipment, documenting fault isolation, corrective work, and final operational tests.

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.
  • Set up and test industrial equipment to ensure that it functions properly.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Telecommunications Equipment Installers and Repairers, Except Line Installers

Operational testing and troubleshooting of SHF satellite terminals and related baseband equipment support telecommunications circuit diagnosis and equipment verification.

How to prepare: Practice tracing faults on commercial telecommunications equipment using its circuit diagrams and test meters, then verify the repaired equipment against its 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.
