Chapter III III-2 JP 3-0 c. While information operations (IO) is not a separate function, the JFC and staff apply the IO core, supporting, and related capabilities across the joint functions and independently in some cases. Some IO capabilities are offensive in application, such as computer network attack (CNA). Operations security (OPSEC) is an example of a defensive capability, and relates to the protection function. Regardless of these alignments, integration and synchronization across IO capabilities and actions is essential to many aspects of joint operations. For example, the commander and staff integrate public affairs (PA) and the commander’s defense support to public diplomacy (DSPD) with other IO actions to enable the commander’s communications strategy. For a more detailed discussion of IO, see JP 3-13, Information Operations. 2. Command and Control a.
