Veteran
Military veterans, i.e., a person who has served or is serving in the armed forces, and has
direct exposure to acts of military conflict, commonly known as
war veterans (although not all military conflicts, or areas in which armed combat takes place, are necessarily referred to as "wars").
The most common usage is for
former armed services personnel. A
veteran is one who has served in the armed forces,
especially one who has served in combat. It is especially applied to those who served for an entire career, usually of 20 years or more, but may be applied for someone who has only served one
tour of duty.
A common misconception is that only those who have served in combat or those who have retired from active duty can be called military veterans.
