Mark Clodfelter is a Professor of Military Strategy at the National War College in Washington, DC. A former US Air Force officer, he served in radar assignments in South Carolina and Korea during a 23-year Air Force career devoted largely to teaching. He twice taught history at the US Air Force Academy, ultimately serving as the Academy's director of military history. From 1991-1994, he was part of the initial cadre of instructors at Air University's School of Advanced Air and Space Studies (SAASS). He next became Professor of Aerospace Studies and Commander of the Air Force ROTC detachment at the University of North Carolina--a true hardship tour for the native North Carolinian. He began teaching at National War College in 1997, first in uniform, and since 2000 as a civilian professor. Mark has published extensively on air power topics. He has received several writing awards, and many of his publications are used in professional military education courses in the US and NATO countries. In 1996, US Air Force Chief of Staff General Ronald Fogleman placed "The Limits of Air Power" on his intermediate reading list; in 2007, the RAF Chief of the Air Staff, Air Chief Marshal Sir Glenn Torpy, placed the paperback edition of "Limits" on his "top ten" reading list for that year. Mark has recently completed "Beneficial Bombing: The Progressive Foundations of American Air Power, 1917-1945," a book analyzing how progressive ideals influenced the American approach to strategic bombing before and during World War II, and why those progressive notions have endured to the present in the US Air Force.He has a BS in European History from the Air Force Academy (1977), an MA in Military History from the University of Nebraska (1983), and a PhD in American History from the University of North Carolina at Chapel Hill. He is a die-hard fan of North Carolina basketball, Air Force Academy football, and St. Louis Cardinals baseball.
