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 Line Installers and Repairers

Installing, maintaining, isolating faults in, and restoring fixed cable distribution systems transfers directly to telecommunications line installation and repair.

How to prepare: Prepare a practical work sample showing how you test a cable, interpret the results, locate a fault, and verify the repair.

What the civilian work involves
  • Set up service for customers, installing, connecting, testing, or adjusting equipment.
  • Inspect or test lines or cables, recording and analyzing test results, to assess transmission characteristics and locate faults or malfunctions.
  • Measure signal strength at utility poles, using electronic test equipment.
Civilian tools and software (examples)
  • Microsoft Excel

Computer Network Support Specialists

LAN/WAN infrastructure support, fault isolation, and network performance analysis provide a foundation for diagnosing civilian network connectivity problems.

How to prepare: Build a small Windows or Linux network lab and document diagnostic tests that distinguish cable faults from operating-system configuration problems.

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)
  • Microsoft Windows
  • Linux
