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.

Interpreters and Translators

Transcribing and translating intercepted foreign communications transfers directly to language work that preserves meaning and uses terminology accurately.

How to prepare: Build a translation portfolio from public material in your language pair, including a terminology glossary and an audio transcription sample.

What the civilian work involves
  • Listen to speakers' statements to determine meanings and to prepare translations, using electronic listening systems as necessary.
  • Compile terminology and information to be used in translations, including technical terms such as those for legal or medical material.
  • Refer to reference materials, such as dictionaries, lexicons, encyclopedias, and computerized terminology banks, as needed to ensure translation accuracy.
Civilian tools and software (examples)
  • Microsoft Word
