Most experts agree that no genuine military transformation or revolution will occur without a corresponding change in operational concepts. Merely replacing old equipment with new is not enough. Militaries must also develop new ways to link tactical actions to strategic ends. For this reason Rapid Decisive Operations (RDO), an emerging concept currently under development by the Joint Futures Lab (J9) of Joint Forces Command, is particularly important for the transformation of U.S. military forces today. An innovative and viable concept will not only stimulate the development of new technologies; it will also help balance the advantages and disadvantages that the introduction of such technologies always entails. On the other hand, a flawed concept will only lead to frustration in training and disappointment in combat as results fail to match expectations.
