A key challenge facing the future Air Force is how to nearly continuously deploy relatively small-scale forces for peacekeeping and humanitarian relief missions while maintaining the capability to win major theater wars. In response to this challenge, the Air Force has developed the concept of an Expeditionary Aerospace Force (EAF) to deal with the range of expected missions.

This framework must integrate logistics, mobility, and operational planning across echelons, commands, and phases of warfare. The report discusses how integrated Agile Combat Support planning aimed at mid-term or strategic decisions can enhance the effectiveness and efficiency of EAF operations. The authors provide an example of use of the ACS planning framework to evaluate support alternatives for a strike AEF deployment to
