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.

Lawyers

Courts-martial litigation, legal assistance, and command legal advice transfer directly to civilian client representation and legal counseling.

How to prepare: Review the intended jurisdiction’s admission or reciprocity rules against your existing credentials and identify any remaining admission steps. Lawyers typically need a law degree and state licensure; most jurisdictions require an accredited J.D., federal-court admission rules differ, and character and continuing legal education requirements may apply.

What the civilian work involves
  • Interpret laws, rulings and regulations for individuals and businesses.
  • Represent clients in court or before government agencies.
  • Evaluate findings and develop strategies and arguments in preparation for presentation of cases.
Civilian tools and software (examples)
  • Microsoft Office software
  • Adobe Acrobat
