Military
A military is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniforms. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as the defense of the state and its interests against external armed threats [Wikipedia].
Armed force is a constituent element of a country’s combined military services. Modern armed forces are commonly divided into specialized branches dealing with land, naval, and air warfare [Online Encyclopedia Britannica].
Each branch of the military also has reserve personnel. The National Guard is organized and controlled by the states and is often used to assist in disaster or state emergencies. Reserve and National Guard personnel typically work a civilian non-military jobs. Still, they are trained to be prepared to be called to full-time active military duty if the country is in need [National Geographic].
