United States of America

Military branches:

Department of the Army, Department of the Navy (includes Marine Corps), Department of the Air Force note:  the Coast Guard is normally subordinate to the Department of Transportation, but in wartime reports to the Department of the Navy Editor's Note:  In addition to the military operated by the federal government, each state in the union also has its own militia (National Guard and/or State Guard) which may be called upon by the State Governor for self-defense or during a natural disaster. The federal government has created the National Guard program in which the states receive federal money to help pay for the state militia in exchange for the ability to call upon the state militia in time of need. The National Guard may be called upon by the State Governor or the President of the United States, but whoever calls them first has complete control of the state militia. Once the state calls the National Guard, the federal government cannot take control away from the state until the state demobilizes the National Guard and vice versa. Some states, like Texas, also have an independent State Guard which can only be called upon by the State Governor, and cannot be called into service by the federal government.
