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.

Paralegals and Legal Assistants

Military experience researching legal matters, preparing wills and powers of attorney, maintaining files, and interacting with clients aligns directly with paralegal support work.

How to prepare: Build a practice portfolio using fictional client information that includes a legal research summary, a sample document, and an organized case file.

What the civilian work involves
  • Prepare affidavits or other documents, such as legal correspondence, and organize and maintain documents in paper or electronic filing system.
  • Prepare, edit, or review legal documents, including legislation, briefs, pleadings, appeals, wills, contracts, and real estate closing statements.
  • Investigate facts and law of cases and search pertinent sources, such as public records and internet sources, to determine causes of action and to prepare cases.
Civilian tools and software (examples)

Court, Municipal, and License Clerks

Military law-office experience maintaining files, checking documents for accuracy, interacting with clients, and managing supplies transfers to court-clerk administrative work.

How to prepare: Use a target court's publicly available forms and filing instructions to practice an intake workflow that checks completeness and organizes submitted documents.

What the civilian work involves
  • Perform administrative tasks, such as answering telephone calls, filing court documents, or maintaining office supplies or equipment.
