In a mock raid on a fake village, the US Army unveiled parts of its high-tech Future Combat Systems, demonstrating equipment that aims to make soldiers' work safer. The exercise was the first public glimpse of a series of camera mounted-robots, small unmanned planes, radios that can send text messages and other equipment that Army and defense officials say will make combat safer for US personnel. As soldiers charged toward the buildings, they sent in a camera-mounted robot, called a SUGV or small unmanned ground vehicle, to see what they were facing. The images were relayed in real time to field commanders, who described them to forward soldiers. Images from the small unmanned aerial vehicle were also sent to the battlefield in real time.
