Colonel Ethan Diven chats with Sean Kalic, the General George C. Marshall chair of Military History at the U.S. Army Command and General Staff College, about how the college has served as the intellectual core of the Army’s learning enterprise since its founding in 1881.   

Known as America’s “School for War” at Fort Leavenworth, Kansas, the CGSC has continuously evolved to deliver cutting-edge warfighting capability to America’s armed forces. Diven and Kalic discuss how college leadership drives the educational transformation by enabling its graduates to employ critical thinking and emerging technologies to solve complex problems and achieve strategic objectives.    

The CGSC’s mission to train, educate, and mentor tomorrow’s leaders remains a critical capability for the U.S. military as it seeks to defeat diverse threats in an era of accelerating change.   

Diven serves as the CGSC’s commandant and has a distinguished military career. He graduated from the Command and General Staff College and the Joint Advanced Warfighting School and has extensive operational experience with various military units, including deployments to Iraq, Afghanistan, and Africa.   

Kalic is a historian and professor in the Department of Military History at the Army Command and General Staff College and has a doctorate in history from Kansas State University. He is also the author of seven books.
