The United States Army National Guard (USANG) is part of the U.S. National Guard. It is divided up into subordinate units that are stationed in each of the 50 states and territories and operate under their respective state governors.
The Army National Guard may be called for active duty by state governors or territorial commanding generals to help respond to situations such domestic emergencies and disasters as hurricanes, tornadoes, floods, and earthquakes. In recent years, the Guard has been called upon to help restore civil stability in the wake of riots in areas such as Baltimore, Maryland, Michigan and Dallas, Texas. The Guard served to help reinforce local law enforcement and provide a sense of security for local residents.
With the consent of state governors, members or units of the Army National Guard may be appointed, temporarily or indefinitely, to be federally recognized armed force members, in the active or inactive service of the United States. If federally recognized, the member or unit becomes part of the Army National Guard of the United States, which is a reserve component of the United States Army, and part of the National Guard of the United States.
Army National Guard of the United States units or members may be called for federal active duty in times of Congress-sanctioned war or national emergency. The President may also call members and units of state Army National Guard, with the consent of state governors to:
- Repel an invasion into the U.S. by a foreign country or terrorist organization
- Suppress rebellion or danger of a rebellion by citizens against the authority of the federal government
- Execute federal laws if the United States or any of its states or territories are invaded or is in danger of invasion by a foreign nation
- Or if the President is unable with the regular armed forces to execute the laws of the United States
Because both state Army National Guard and the Army National Guard of the United States relatively go hand-in-hand, they are both usually referred to as just the Army National Guard.
