In April 1994, the Army War College and the Strategic Studies Institute hosted the Fifth Annual Strategy Conference. The theme of this year's conference was "The Revolution in Military Affairs (RMA): Defining an Army for the 21st Century." Jeffrey R. Cooper presented the following paper as part of an opening panel which sought to define the RMA. Mr. Cooper urges defense planners to determine what strategic--as opposed to operational--benefits might be derived from the RMA. He contends that making the internal reforms that will be required will be as challenging as coming to terms with the operational and strategic implications of the new technologies. The first requirement is to understand the parameters and dynamics of this particular revolution in military affairs. Mr. Cooper puts the RMA in historical perspective by discussing the relationships among technology, socioeconomic, and political change, and their implications for warfare during the Napoleonic era, the mid-19th century, and World Wars I and II. He argues that, in the past, dramatic technological change affected warfare in different ways.
