This book represents some of the thinking by students at the U.S. Army War College, considering the nature and direction of transformation. They consider how the transformed joint services of the United States should employ force in the 21st century. The services are exploring concepts such as Effects Based Operations and Rapid Decisive Operations to move swiftly and strike vigorously to secure victory in the coming decades. At the same time the nation and its armed forces are developing new concepts of homeland security to defend the country in the war on terrorism. Officers who participated in the Advanced Strategic Art Program (ASAP) during Academic Year 2002 wrote the individual chapters.
