In accordance with Army Regulation 870-5 and TRADOC Regulation 870-1, the Combat Studies Institute provides a wide range of military historical and educational support to the Combined Arms Center, Training and Doctrine Command, and the United States Army at large. CSI researches, writes, and publishes — through the CSI Press — original interpretive works on issues of relevance to the Army and the defense of the Nation. The Institute conducts an Oral History program that targets Command and General Staff College students and faculty, as well as permanent party and visitors of the Combined Arms Center that focuses on their respective operational experiences. CSI conducts a dynamic Staff Ride program for the Army that offers live and virtual battlefield Staff Rides while also serving as TRADOC's agent for information and assistance with how organizations can conduct their own facilitated Staff Rides. The Institute is also charged with sustaining the quality of the instruction of military history throughout the TRADOC school system and does this by assisting the TRADOC Chief Historian with program inspections, assessing and revising training support packages, conducting "train-the-trainer" courses, and by serving as the TRADOC proponent for the Military History Instructors' Courses (MHIC) and the Army's Field Military Historian Course (ASI 5X). CSI also exercises oversight responsibilities for the Combined Arms Center Command History Office and Fort Leavenworth’s Frontier Army Museum. CSI consists of five functional Teams: the Research and Publications Team, the Military History Instructional Support Team, the Staff Ride Team, the CAC Command History Office, and the Frontier Army Museum.
