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.

Mobile Heavy Equipment Mechanics, Except Engines

Experience maintaining and operating construction equipment transfers directly to mobile heavy equipment maintenance work.

How to prepare: Compare your documented equipment maintenance experience with a target employer's machinery, then select hands-on training for unfamiliar equipment.

What the civilian work involves
  • Repair and replace damaged or worn parts.
  • Test mechanical products and equipment after repair or assembly to ensure proper performance and compliance with manufacturers' specifications.
  • Operate and inspect machines or heavy equipment to diagnose defects.
Civilian tools and software (examples)
  • Maintenance management software
  • Recordkeeping software

First-Line Supervisors of Mechanics, Installers, and Repairers

Construction management experience focused on vehicle and equipment maintenance provides a foundation for supervising an equipment maintenance shop.

How to prepare: Build a work-history summary identifying any repair-quality oversight and employee supervision you performed, and use it to target equipment-shop supervisory openings.

What the civilian work involves
  • Inspect, test, and measure completed work, using devices such as hand tools or gauges to verify conformance to standards or repair requirements.
  • Inspect and monitor work areas, examine tools and equipment, and provide employee safety training to prevent, detect, and correct unsafe conditions or violations of procedures and safety rules.
  • Monitor employees' work levels and review work performance.
Civilian tools and software (examples)
  • Microsoft Excel
