Weapons of mass destruction. Accelerating rates of technological change. Transnational organizations. Cyber warfare. Regional and globa competitor states. Violent extremism. Antiaccess and area-denial threats. Fiscal constraints. These are just a few of the security environmental conditions within which the future joint force will operate. To be effective in such an unpredictable, complex, and dangerous world and to protect U.S. global interests, the joint force must operate in smaller units capable of aggregating at a moment’s notice, reconfiguring in response to environmental challenges and opportunities, and disaggregating upon mission completion. These adaptable military responses must occur at increasing rates of speed leveraging insightful prepositioning of military forces around the world and rapid expeditionary basing. The ability to operate effectively in such a manner is the basis for the concept of globally integrated operations that General Martin Dempsey, Chairman of the Joint Chiefs of Staff, is promoting as a way to project decisive force to protect U.S. global interests.
