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.

Radio, Cellular, and Tower Equipment Installers and Repairers

Troubleshooting and repairing ground radio and tactical wideband systems transfers directly to radio transmission equipment installation and repair.

How to prepare: Complete a hands-on exercise in transmission-component sweep testing and installation inspection using civilian equipment specifications.

What the civilian work involves
  • Test operation of tower transmission components, using sweep testing tools or software.
  • Install all necessary transmission equipment components, including antennas or antenna mounts, surge arrestors, transmission lines, connectors, or tower-mounted amplifiers (TMAs).
  • Read work orders, blueprints, plans, datasheets or site drawings to determine work to be done.

Telecommunications Equipment Installers and Repairers, Except Line Installers

Diagnosing, repairing, and assisting with installation of wideband and intercommunication systems provides a foundation for civilian telecommunications equipment service.

How to prepare: Practice isolating faults and verifying repairs on civilian data or telephone equipment using circuit diagrams and test meters.

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 Electronic Engineering Technologists and Technicians

Modifying and maintaining electronic systems, researching faults, and ordering repair parts transfers to the equipment-service side of electronics technician work.

How to prepare: Build a bench troubleshooting project that documents fault isolation, component replacement, and post-repair performance tests against a schematic.

What the civilian work involves
  • Modify, maintain, or repair electronics equipment or systems to ensure proper functioning.
  • Set up and operate specialized or standard test equipment to diagnose, test, or analyze the performance of electronic components, assemblies, or systems.
  • Identify and resolve equipment malfunctions, working with manufacturers or field representatives as necessary to procure replacement parts.
