An Airborne Command Post (ACP) is a mobile command center located on an aircraft, designed to provide leadership and coordination during military operations. It allows commanders to maintain situational awareness and make critical decisions while airborne, ensuring effective communication with ground forces and other units. Typically equipped with advanced communication systems, the ACP can relay information and directives in real-time. This capability is crucial during emergencies or conflicts, as it enhances the operational effectiveness of military strategies. The use of an ACP is often associated with military aircraft like the E-4B Nightwatch or E-6B Mercury.
