This book investigates the modem changes in organization, concepts and doctrine in view of the recent discussion concerning revolution in military affairs. The concept presented is one that proposes that the changes are evolutionary in nature when compared against certain criteria requisite for true revolutions in military affairs. The characteristics required for a true revolution in military affairs are explained and a historical comparison of the evolution of the United States World War II armored division is used to expound on these characteristics. This book emphasizes the importance of the impact of revolutions in military affairs and their impact on the military as an organization. This work compares the changes now occurring with the established criteria to demonstrate the evolutionary nature of these changes.
