The Wisconsin Army National Guard is made up of approximately 7,700 soldiers including a headquarters staff in Madison and four major commands located throughout 67 Wisconsin communities: the 32nd “Red Arrow” Infantry Brigade Combat Team headquartered at Camp Douglas; 64th Troop Command, Madison; 157th Maneuver Enhancement Brigade, Milwaukee; and the 426th Regiment (RTI) Regional Training Institute, Fort McCoy. The Army National Guard (ARNG) is one of the seven reserve components of the United States armed forces. It is also the organized militia of 54 separate entities: the 50 states, the territories of Guam and the U.S. Virgin Islands, the Commonwealth of Puerto Rico, and the District of Columbia. Administered by the National Guard Bureau (a joint bureau of the departments of the Army and Air Force), the ARNG has both a federal and state mission. The dual mission, a provision of the U.S. Constitution and the U.S. Code of laws, results in each Soldier holding membership in both the National Guard of his or her state and in the U.S. Army.
