The Helmet Mounted Radar Program hopes to supply soldiers with 360-diploma protection by way of Shifting Goal Indicator sensors that "see" motion up to 25 meters (eighty two ft) away [supply: Dillow]. Your entire system should weigh less than 2.5 pounds (1.1 kilograms), with less than half of that load affixed to the helmet [source: Fallon]. Thus equipped, soldiers will be capable to detect movement that might tip them off to potential ambushes.
