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.

Automotive Service Technicians and Mechanics

Inspection, diagnostics, repair, and component rebuilding on military and commercial general-purpose vehicles transfer directly to automotive service work.

How to prepare: Compare your documented vehicle repairs with a local automotive shop's services and arrange hands-on training for unfamiliar diagnostic equipment.

What the civilian work involves
  • Inspect vehicles for damage and record findings so that necessary repairs can be made.
  • Test drive vehicles and test components and systems, using equipment such as infrared engine analyzers, compression gauges, and computerized diagnostic devices.
  • Test and adjust repaired systems to meet manufacturers' performance specifications.

Bus and Truck Mechanics and Diesel Engine Specialists

Special-purpose vehicle diagnostics, component rebuilding, and metal welding provide transferable repair experience for truck maintenance.

How to prepare: Build a repair-history summary identifying the vehicles, engines, and components you serviced, then review it with a truck shop to identify model-specific diagnostic training.

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.
  • Adjust and reline brakes, align wheels, tighten bolts and screws, and reassemble equipment.
  • Attach test instruments to equipment, and read dials and gauges to diagnose malfunctions.
Civilian tools and software (examples)
  • Computerized maintenance management system software CMMS
  • Cummins INSITE

Mobile Heavy Equipment Mechanics, Except Engines

Inspection, diagnostics, and assembly repair on material handling equipment and base-maintenance vehicles overlap with mobile heavy-equipment repair.

How to prepare: Compare the equipment you maintained with a prospective employer's fleet and select manufacturer service training for an unfamiliar equipment type.

What the civilian work involves
  • Repair and replace damaged or worn parts.
  • Operate and inspect machines or heavy equipment to diagnose defects.
  • Dismantle and reassemble heavy equipment using hoists and hand tools.
Civilian tools and software (examples)
  • Maintenance management software

Notes & Sources

  • Choose among these trades based on the vehicles and components actually maintained; the specialty description does not establish individual diesel-engine experience or experience with every listed vehicle type.
