This United States Air Force USAF manual, Air Force Doctrine Publication AFDP 3-36 Air Mobility Operations June 2024, describes airlift, air refueling, aeromedical evacuation, and air mobility support and contingency response operations. Air mobility is the rapid movement of resources to, from, or within, a theater by air. It constitutes one element of the strategic mobility triad that includes strategic airlift, strategic sealift, and pre-positioned stocks (PREPO). Together, these elements provide the air, sea, and land infrastructure of the Defense Transportation System (DTS) that supports the Department of Defense's (DoD's) transportation capability for the joint force. Air mobility operations are categorized as either intertheater-operations between two or more geographic areas of responsibility (AORs), or intratheater-operations exclusively within one AOR. Effective integration and synchronization of intertheater and intratheater air mobility operations is crucial to positioning joint forces to a position of advantage over an enemy, adversary, or in support of joint objectives.
