These proceedings are the third volume to be published in a series generated by the annual military history symposium sponsored by the US Army Training and Doctrine Command (TRADOC). This year's symposium, hosted by the Combat Studies Institute, was held 2-4 August 2005 at Fort Leavenworth, Kansas. The 2005 symposium's theme was An Army at War: Change in the Midst of Conflict. As this title indicates, presentations at this event focused on how an Army changes while concurrently fighting a war. Changing an Army in peacetime is difficult enough. Transformation can include changes to the personnel system, the turning in old and the fielding of new equipment, new training requirements, and at times, learning an entirely new way of viewing the enemy and the battle space in which operations will occur. Practical and cultural changes in an Army always cause tremendous turbulence and angst, both inside and outside of the Army.
