About the Garrison
FORT LEAVENWORTH
Fort Leavenworth, Kansas is the oldest continuously operating military installation west of the Mississippi River. Built in 1827, it is the second oldest active United States Army post west of Washington D.C., and the oldest permanent settlement in Kansas. This historic post, noted for its campus setting, open green spaces and hometown character, is the home of the U.S. Army's Combined Arms Center (CAC). CAC, as a major subordinate headquarters of the U.S. Army Training and Doctrine Command, has often been referred to as the "Intellectual Center of the Army". It is, in many regards, "home base" for most field grade officers across the Army.
