Doctrine comes in several levels: Service doctrine is written for and used by a single service to govern its own procedures, organization, and employment of forces. The Air Force publishes its own doctrine to guide how it conducts air and space power, trains its personnel, and plans missions. That focus on a single service and its way of operating is what makes Air Force Doctrine an example of Service Doctrine. Joint Doctrine, in contrast, covers how all services work together in combined operations and is coordinated across the Joint Chiefs. Multiservice Doctrine is intended for several services to use in joint or combined contexts but is not exclusive to one; multinational Doctrine addresses coalition operations with foreign partners. Because the material in Air Force Doctrine is tailored to the Air Force alone, it best fits the Service Doctrine category.
