The U.S. Army Combined Arms Center (USACAC) is located at Fort Leavenworth and provides leadership and supervision for leader development and professional military and civilian education; institutional and collective training; functional training; training support; battle command; doctrine; lessons learned and specified areas the Commanding General, United States Army Training and Doctrine Command (TRADOC) designates in order to serve as a catalyst for change and to support developing relevant and ready expeditionary land formations with campaign qualities in support of the joint force commander.

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).

At present, this mission is divided between preparing the Army for the Global War on Terrorism and transforming it to meet future threats.

Schools, centers and specialized activities are spread across the country and are responsible for executing a portion of the CAC mission.

In general, each of these organizations is responsible for the training of specific branch skills (such as "Infantry") and serving as the Army's functional expert in that area.
