The face of war has changed. Enemy lines blur, and there is no longer a clear opponent. New enemies and new threats require a new type of warfare - a new type of soldier. Enter the Ghosts. In 2013, the U.S. Army will implement the Integrated Warfighter System (IWS), evolving what we know as the modern soldier. IWS combines advanced weapon systems, satellite communication devices and enhanced survivability into one fully integrated combat system.
