A veteran is generally a person who once served in a country’s armed forces and is no longer on active duty, usually with a discharge that is not dishonorable.

Basic definition

  • In everyday language, a veteran is anyone who previously served in the military (army, navy, air force, marines, coast guard, etc.) and has since left service.
  • In many legal and benefits contexts (like in the U.S.), the person must have served on active duty and been discharged under conditions “other than dishonorable” to be counted as a veteran for official purposes.

Legal and benefits context

  • U.S. federal rules often define a veteran as a former member of the armed forces who served on active duty and was released under honorable, general, or “under honorable conditions” discharge types.
  • Some places add minimum service periods (for example, 90 or 180 days of active duty, sometimes including at least one day during a designated “wartime” period) when deciding who qualifies for state or local veterans’ benefits.

Not just combat service

  • A common misconception is that only people who fought in combat or completed a full 20‑year career are veterans, but anyone who served and left the military under qualifying conditions can be considered a military veteran.
  • Support roles, non‑deploying units, and peacetime service can all count as veteran service; combat experience is not required for the core definition.

Broader everyday use

  • In general English, “veteran” can also mean someone with long experience in a field, like a veteran politician or a veteran teacher, even outside the military context.
  • That broader meaning is common in news and conversation, but when people ask “who is a veteran” without extra context, they usually mean former military personnel.
