Recent military operations in Afghanistan and Iraq were characterized by the rapid defeat of enemy military forces, by relatively small deployments of American forces, and by a very limited destruction of the critical civilian infrastructure. This success can be credited in large part to the ongoing transformation of the U.S. military evident in its effective use of information superiority, precision strike, and rapid maneuver on the battlefield. The Armed Forces were not nearly as well prepared to respond promptly to the lawlessness, destruction of the civilian infrastructure, and attacks on coalition forces that followed hard on the defeat of the Iraqi military. This has set back plans to restore essential services and to pass the reins to a representative Iraqi government. Moreover, the failure to establish security concurrently with the defeat of the Iraqi military may well have emboldened those who oppose the United States, United Kingdom, and even United Nations presence. It is precisely the success of the U.S. military in transforming its forces to execute rapid decisive operations that makes it imperative to transform how it prepares for and executes stabilization and reconstruction (S AND R) operations. The very rapid defeat of the enemy military means the United States must be ready to field the resources needed to secure stability and begin the reconstruction process promptly-ideally concurrently-with the end of major combat. This can only be done if planning for the stabilization and reconstruction operations is integrated into planning for the conflict from the beginning and if the right skills are in theater to begin operations concurrently with the surrender or collapse of the enemy military.
