Its primary mission is to develop and integrate training, doctrine, and leader development for combined arms operations, which involve the coordinated use of different military branches and units. The CAC plays a vital role in preparing soldiers and leaders for modern warfare. Additionally, the CAC oversees the Army's Command and General Staff College, which educates officers on operational art and strategy.
