Air Force Doctrine Document (AFDD) 2-0, Global Integrated Intelligence, Surveillance, and Reconnaissance (ISR) Operations, is the Air Force's keystone doctrinal publication on global integrated ISR and defines how the Service plans and conducts these operations to enable Joint Operations. It compiles the best practices of how an Airman conducts and employs ISR capabilities and why global integrated ISR is unique. The three chapters define global integrated ISR, the command relationships and authorities that enable it, and how these operations are planned and conducted.
