As the Army’s key integrating manual for Information Operations (IO), this manual prescribes IO doctrine and tactics, techniques, and procedures (TTP). It also establishes doctrine and TTP for the IO elements of operations security and military deception. It implements joint IO doctrine established in JP 3-13, Joint Doctrine for Information Operations; JP 3-54, Joint Doctrine for Operations Security; and JP 3-58, Joint Doctrine for Military Deception. It establishes the following as the definition of IO used by Army forces: Information operations is the employment of the core capabilities of electronic warfare, computer network operations, psychological operations, military deception, and operations security, in concert with specified supporting and related capabilities, to affect or defend information and information systems, and to influence decision making.
