The joint doctrine established in this publication applies to unified commands and their subordinate commands and those joint task forces that may be established by the President, Secretary of Defense, or commander of a unified command for the conduct of specific operations. The doctrine is broadly stated to fit the widely varying situations and areas in which counterair operations may be undertaken. The influence of geography, international agreements, alliance command structure, enemy capabilities, and concepts of operations are such that military strategies may vary considerably between areas. Force employment plans that support the military strategy must be developed in more detail for each theater by the commander exercising operational command. Plans must consider the likelihood of coalition warfare and the need for further development of a combined doctrine to ensure compatibility, if not interoperability, of future command, control, communication, intelligence, and weapon and support systems.
