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

Maintenance of NAVMACS II and associated shipboard data equipment transfers to maintaining civilian telecommunications equipment.

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

Organizational-level maintenance of shipboard data, communications, and navigation equipment provides a foundation for commercial electronics repair.

How to prepare: Practice diagnosing a faulty commercial electronic unit with its service documentation and test equipment, then record the repair and verification 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.
  • 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)
