Book excerpt: The U.S. military is no longer based on a Cold War self-sufficient model. Today's armed forces are a third smaller than they were during the Cold War, and yet are expected to do as much if not more than they did during those years. As a result, a transformation is occurring in the way the U.S. government expects the military to conduct operations—with much of that transformation contingent on the use of contractors to deliver support to the armed forces during military campaigns and afterwards. Contractors and War explains the reasons behind this transformation and evaluates how the private sector will shape and be shaped by future operations. The authors are drawn from a range of policy, legislative, military, legal, and academic backgrounds. They lay out the philosophical arguments supporting the use of contractors in combat and stabilization operations and present a spectrum of arguments that support and criticize emergent private sector roles. The book provides fresh policy guidance to those who will research, direct, and carry out future deployments.
