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.

First-Line Supervisors of Mechanics, Installers, and Repairers

Immediate supervision of technicians performing strategic weapons assembly, testing, repair and calibration transfers directly to maintenance workforce supervision.

How to prepare: Compare maintenance-supervisor postings in a target industry to identify trade-specific knowledge and hands-on repair expectations before selecting technical training.

What the civilian work involves
  • Monitor employees' work levels and review work performance.
Civilian tools and software (examples)
  • Microsoft Excel
  • Microsoft Project

Supply Chain Managers

Integrating maintenance, transportation, enterprise supply chains and production operations transfers to coordinating civilian material flows across operational functions.

How to prepare: Complete a civilian material-requirements-planning exercise that links inventory availability, production needs and transportation schedules.

What the civilian work involves
  • Determine appropriate equipment and staffing levels to load, unload, move, or store materials.
  • Manage activities related to strategic or tactical purchasing, material requirements planning, controlling inventory, warehousing, or receiving.
  • Develop procedures for coordination of supply chain management with other functional areas, such as sales, marketing, finance, production, or quality assurance.
