A no-nonsense treatment of information operations, this handbook makes clear what does and does not fall under information operations to how the military plans and executes such efforts, and what the role of IO ought to be in the "war of ideas." The author provides detailed accounts of the doctrine and practice of the five core information operations capabilities (psychological operations, military deception, operations security, electronic warfare, and computer network operations) and the three "related" capabilities (public affairs, civil-military operations, and military support to public diplomacy). The discussion of each capability includes historical examples, explanations of tools and forces available, and current challenges faced by that community. An appendix of selected excerpts from military doctrine ties the work firmly to the military theory behind information operations.The author argues that contemporary IO's mixing of capabilities focused on information content with those focused on information systems conflates "apples" with the "apple carts."This important study concludes that information operations would be better poised to contribute to the war of ideas if IO were reorganised, separating content capabilities from systems capabilities and separating the employment of "black" (deceptive or falsely attributed) information from "white" (wholly truthful and correctly attributed) information.
