The Northrop Grumman E-8 Joint Surveillance Target Attack Radar System is a retired United States Air Force (USAF) airborne ground surveillance, battle management and command and control aircraft. It tracks ground vehicles and some aircraft, collects imagery, and relays tactical pictures to ground and air theater commanders. The aircraft was operated by both active duty USAF and Air National Guard units and also carried specially trained U.S. Army personnel as additional flight crew until its retirement in 2023.

Battle command (BC) is the discipline of visualizing, describing, directing, and leading forces in operations against a hostile, thinking, and adaptive enemy. Battle command applies leadership to translate decision into actions, by synchronizing forces and warfighting functions in time, space, and purpose, to accomplish missions. Battle command refers both to processes triggered by commanders and executed by soldiers and to the system of systems (SoS) that directly enables those processes.
