Argues that from 1989 through 2005 the United States Army attempted, and largely achieved, a centrally directed and institutionally driven transformation relevant to ground warfare that exploited Information Age technology, adapted to post-Cold War strategic circumstances, and integrated into parallel Department of Defense efforts. The process not only modernized equipment, it also substantially altered doctrine, organization, training, administrative and logistical practices, and the service culture. The resultant digitized expeditionary Army was as different from the late Cold War Army as the late Cold War Army was from that of the early Cold War or from the mobilization-based Armies of World Wars I and II. The book further contends that the digitized expeditionary Army has withstood the test of combat, performing superbly with respect to deployment and high-end conventional combat and capably with respect to low-intensity conflict.
