The Army National Guard is a military reserve force in the United States formed by the Dick Act. The Army National Guard may be called up for active duty by the state governors or territorial commanding generals to help respond to domestic emergencies and disasters, such as those caused by hurricanes, floods, and earthquakes. With the consent of the respective states' governors, the Army National Guard can become a reservist arm of the U.S. military, supporting both the regular army and air force in the field.
