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

Organizational maintenance of DSCS and FLTSATCOM satellite ground terminals provides directly related communications-equipment maintenance experience.

How to prepare: Complete a hands-on telecommunications repair lab covering circuit fault isolation and post-repair testing on civilian equipment.

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.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Maintenance of satellite communications equipment provides an electronics-maintenance foundation for moving into commercial and industrial equipment repair.

How to prepare: Take a practical industrial-electronics troubleshooting course that includes testing faulty equipment and documenting repairs.

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.
  • Inspect components of industrial equipment for accurate assembly and installation or for defects, such as loose connections or frayed wires.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS
