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.

Stockers and Order Fillers

Receiving, storing, and issuing ammunition transfers directly to civilian stock storage and material distribution work.

How to prepare: Build a resume example showing how you received, stored, and issued materials, then target stockroom or warehouse openings rather than customer-facing retail positions.

What the civilian work involves
  • Complete order receipts.
  • Issue or distribute materials, products, parts, and supplies to customers or coworkers, based on information from incoming requisitions.
  • Stock shelves, racks, cases, bins, and tables with new or transferred merchandise.

Explosives Operator (Federal)

Ammunition maintenance and modification duties overlap with the federal occupation's ammunition renovation and modification work.

How to prepare: Document your ammunition-maintenance and modification assignments separately from storage and issue duties, then compare that record with a federal 6502 vacancy's qualifications.

Notes & Sources

  • Federal occupation 6502 excludes receipt, storage, and issue as well as munitions destruction; its grading standard establishes neither your qualifying federal grade nor authorization for commercial blasting.
