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 Communications Equipment Repairer

Organizational-level maintenance and operational testing of TSCOMM transceivers and receivers transfer directly to radio equipment servicing and testing.

How to prepare: Complete a supervised bench-servicing exercise on a civilian radio receiver, using its service documentation to record test results and verify operation after repair.

What the civilian work involves
  • Read work orders, blueprints, plans, datasheets or site drawings to determine work to be done.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Maintenance of communications electronics and system operational testing provide a foundation for diagnosing and repairing commercial electronic equipment.

How to prepare: Complete a supervised fault-diagnosis exercise on commercial electronic equipment and produce a repair log with before-and-after test 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.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Computer Network Support Specialists

TSCOMM maintenance involving computers, switches, modems, and data links provides a hardware and connectivity foundation for network troubleshooting.

How to prepare: Build a small IP-network lab and document how you diagnose and resolve a connectivity fault using diagnostic software and equipment.

What the civilian work involves
  • Identify the causes of networking problems, using diagnostic testing software and equipment.
  • Document network support activities.
Civilian tools and software (examples)
  • Linux
  • Microsoft Windows

Notes & Sources

  • The radio path is limited to equipment servicing and testing; documented duties do not establish antenna, mount, transmission-line, or tower-amplifier installation experience or tower-work experience.
