Fort Leavenworth is a United States Army facility located in Leavenworth County, Kansas (just north of the city of Leavenworth) in the upper northeast portion of the state. It is the oldest active U.S. Army post west of the Missouri River, in operation for over 170 years. Fort Leavenworth has been historically known as the "Intellectual Center of the Army."
During the country's westward expansion, Fort Leavenworth was a forward destination for thousands of soldiers, surveyors, immigrants, American Indians, preachers and settlers who passed through. The garrison supports the U.S. Army Training and Doctrine Command (TRADOC) by managing and maintaining the home of the U.S. Army Combined Arms Center (CAC). CAC's mission involves leader development, collective training, Army doctrine and battle command (current and future).
Fort Leavenworth is home to the Military Corrections Complex, consisting of the United States Disciplinary Barracks, the Department of Defense's only maximum security prison, and the Midwest Regional Correctional Facility. In addition, the Fort Leavenworth Garrison supports numerous tenant organizations that directly and indirectly relate to the functions of the CAC, including the Command and General Staff College and the Foreign Military Studies Office.
The fort occupies 5,600 acres (23 km²) and 7,000,000 ft² (650,000 m²) of space in 1,000 buildings and 1,500 quarters.
