The use of unobtrusive civilian contractors is another consequence from the last decade of experience with irregular conflict. I have recently discussed the increasing “civilianization” of warfare. Irregular adversaries have long taken on civilian guise in order to avoid the superior firepower usually wielded by nation-states. U.S. policymakers today find it politically untenable to use conventional military force, especially ground forces, against irregular adversaries. Increasingly more convenient are civilian substitutes such as CIA paramilitaries, contractors, and hired proxies.
