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.

Bus and Truck Mechanics and Diesel Engine Specialists

ACV automotive inspection, maintenance, and repair experience transfers directly to commercial heavy-vehicle maintenance work.

How to prepare: Complete hands-on training in commercial truck diagnostic equipment, using Cummins INSITE as one option.

What the civilian work involves
  • Inspect brake systems, steering mechanisms, wheel bearings, and other important parts to ensure that they are in proper operating condition.
