Today's military has seen an evolution in technology that is creating an entirely new capability to project power through the use of unmanned systems while reducing the risk to human life. The contributions of unmanned systems continue to increase. As of October 2006, coalition Unmanned Aircraft Systems (UASs), exclusive of hand-launched systems, had flown almost 400,000 flight hours in support of Operations Enduring Freedom and Iraqi Freedom, Unmanned Ground Vehicles (UGVs) had responded to over 11,000 Improvised Explosive Device (IED) situations, and Unmanned Maritime Systems (UMSs) had provided security to ports. As a result of these successes, the Quadrennial Defense Review (QDR) emphasized the importance of unmanned systems in the Global War on Terrorism (GWOT).
