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

AS experience troubleshooting diesel engines, transmissions, steering, suspension, and electrical systems transfers directly to diesel fleet repair.

How to prepare: Complete hands-on training with a civilian diesel diagnostic platform such as Cummins INSITE to practice manufacturer-specific fault diagnosis.

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.
  • Raise trucks, buses, and heavy parts or equipment using hydraulic jacks or hoists.
  • Attach test instruments to equipment, and read dials and gauges to diagnose malfunctions.
Civilian tools and software (examples)
  • Cummins INSITE
  • Computerized maintenance management system software CMMS

Stationary Engineers and Boiler Operators

AS maintenance of compressors, pneumatic systems, power-generating equipment, and air-conditioning systems provides a foundation for stationary plant equipment work.

How to prepare: Take a hands-on boiler operations course covering combustion controls, water treatment, and operating gauges to address gaps beyond support-equipment maintenance. Some state and local jurisdictions require equipment-class licenses based on experience and an examination, so check the rules where you intend to work.

What the civilian work involves
  • Operate or tend stationary engines, boilers, and auxiliary equipment, such as pumps, compressors, or air-conditioning equipment, to supply and maintain steam or heat for buildings, marine vessels, or pneumatic tools.
  • Analyze problems and take appropriate action to ensure continuous and reliable operation of equipment and systems.
  • Observe and interpret readings on gauges, meters, and charts registering various aspects of boiler operation to ensure that boilers are operating properly.
Civilian tools and software (examples)
  • Building management system software
