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.

Transportation, Storage, and Distribution Managers

Directing munitions materiel management and support-equipment maintenance transfers to overseeing material operations and equipment upkeep.

How to prepare: Build a civilian operations work sample that translates a munitions materiel-management plan into receiving, storage, testing, and shipping workflows.

What the civilian work involves
  • Supervise the activities of workers engaged in receiving, storing, testing, and shipping products or materials.
  • Inspect physical conditions of warehouses, vehicle fleets, or equipment and order testing, maintenance, repairs, or replacements.
  • Collaborate with other departments to integrate logistics with business systems or processes, such as customer sales, order management, accounting, or shipping.
Civilian tools and software (examples)
  • Microsoft Excel
  • Microsoft Project

Electrical and Electronic Engineering Technologists and Technicians

Maintenance planning for missile guidance and test equipment, together with calibration support, provides a foundation for electronic equipment testing and maintenance.

How to prepare: Complete a hands-on electronics laboratory course focused on schematic reading, test-equipment operation, and fault diagnosis to bridge from maintenance support to bench work.

What the civilian work involves
  • Modify, maintain, or repair electronics equipment or systems to ensure proper functioning.
  • Set up and operate specialized or standard test equipment to diagnose, test, or analyze the performance of electronic components, assemblies, or systems.
  • Read blueprints, wiring diagrams, schematic drawings, or engineering instructions for assembling electronics units, applying knowledge of electronic theory and components.
Civilian tools and software (examples)
