U.S. Army Center of Military History This link opens in a new windowThe Center Of Military History (CMH) is responsible for the appropriate use of history throughout the United States Army. Traditionally, this mission has meant recording the official history of the Army in both peace and war, while advising the Army Staff on historical matters. The Center's work with Army schools ensures that the study of history is a significant part of the training of officers and noncommissioned officers. It also supports the use of history to foster unit pride and give today's soldiers an understanding of the Army's past. he Center thus provides all levels of the Army, as well as other services, government agencies, and the public, with a growing awareness of history that goes well beyond publications alone.
