The military concept of Revolution in Military Affairs (RMA) is a military-theoretical hypothesis, about the future of warfare, often connected to technological and organizational recommendations for change in the United States military and others. Broadly stated, RMA claims that in certain periods of the history of humankind, there were new military doctrines, strategies, tactics and technologies which led to an irrevocable change in the conduct of warfare. Furthermore, those changes require an accelerated adaptation of novel doctrines and strategies.
Especially tied to modern information, communications, and space technology, RMA is often linked to current discussions under the label of Transformation and total systems integration in the U.S. military.
The original theorizing was done by the Soviet Armed Forces in the 1970s and 1980s, particularly by Marshal Nikolai Ogarkov. The United States initially became interested in it through Andrew Marshall, the head of the Office of Net Assessment, a Department of Defense think tank. It slowly gained credence within official military circles, and other nations began exploring similar shifts in organization and technology.
Interest in RMA and the structure of future U.S. armed forces is strong within the China's People's Liberation Army and incorporated to China's strategic military doctrine. Many other militaries have also researched and considered RMA as an organizational concept—e.g., those of Canada, United Kingdom, the Netherlands, Sweden, Australia, New Zealand, South Africa, Singapore, Republic of China (Taiwan), India, Russia, and Germany—but not all militaries due to the significant infrastructure and investment involved.
