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.

Machinists

Military experience fabricating, repairing, and modifying parts transfers to machining parts to specification.

How to prepare: Arrange a hands-on machining skills assessment through a trade school or employer to identify gaps in machine setup, tolerance calculations, and precision measurement.

What the civilian work involves
  • Calculate dimensions or tolerances, using instruments, such as micrometers or vernier calipers.
  • Machine parts to specifications, using machine tools, such as lathes, milling machines, shapers, or grinders.
  • Measure, examine, or test completed units to check for defects and ensure conformance to specifications, using precision instruments, such as micrometers.
Civilian tools and software (examples)
  • Autodesk AutoCAD
  • Dassault Systemes SolidWorks
