Fort Leavenworth, Kansas is the oldest continuously operating military installation west of the Mississippi River. This historic post, noted for its campus setting, open green spaces and hometown character, is the home of the US 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 the majority of field grade officers across the Army.

Since 1882, CAC and its predecessor organizations have been engaged in the primary mission of preparing the Army and its leaders for war. At present, this mission is divided between preparing the Army for the Global War on Terrorism and transforming it to meet future threats.

In order to accomplish these critical missions, CAC develops and integrates Army leader development, doctrine, education, lessons learned, functional training, training support, training development, and proponent responsibilities in order to support mission command and prepare the Army to successfully conduct unified land operations in a joint, inter-agency, inter-governmental, multinational environment.
