Military 

What is the military? In simple terms, the U.S. Armed Forces are made up of the six military branches: Air Force, Army, Coast Guard, Marine Corps, Navy and, most recently, Space Force.

There are three general categories of military people: active duty (full-time soldiers and sailors), reserve & guard forces (usually work a civilian job but can be called to full-time military duty), and veterans and retirees (past members of the military).
