"The end of the Cold War marked the end of an era in United States national security. The bipolar global balance of power, which defined our nation's defensive strategy for more than 30 years, was replaced with the uncertainty of failed nation-states, rogue authoritarian regimes, and international terrorist organizations. Operations in the late twentieth century and early twenty first cnetury [sic] have been characterized by a dramatic increase in the use of C4ISR [Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance] systems, transformation initiatives, and network centric warfare concepts. Joint and Coalition forces showed how effective these systems, initiatives, and concepts can be during major combat operations in Iraq and Afghanistan. A theory of technological synergy is used to describe changes in effectiveness through implementation of technology and organizational change. Multiple systems from space, to aircraft and UAVs [Unmanned Aerial Vehicle], to ground systems are required to empower the Joint Force. Through the successful implementation of these systems, a global C4ISR structure can be described as the primary enabler that empowers Joint Forces to successfully conduct the Global War on Terror."
