The U.S. Army War College provides an excellent environment for selected military officers and government civilians to reflect and use their career experience to explore a wide range of strategic issues. To assure that the research developed by Army War College students is available to Army and Department of Defense leaders, the Strategic Studies Institute publishes selected papers in its Carlisle Papers in Security Strategy Series. The author of this paper argues that the major capability gap in today's force-and vital for future campaigns-is the ability to conduct stabilization. He suggests three areas where Army leaders must make near-term adjustments in the Modular Force to ensure the nation has a truly expeditionary force with the campaign capacity for both rapid decisive operations and stabilization.
