It's often said that a soldier's greatest weapon is his head; now, the U.S. Army plans to sharpen that weapon, installing radar in troops' combat helmets, upgrading one of the oldest pieces of infantry armor into an effective tactical device.

The Helmet Mounted Radar Program aims to provide a near-360-degree field for Moving Target Indicator (MTI) radar sensors that is low-power and can detect a moving threat as far out as 25 meters. The sensor should be integrated into the combat helmet and weigh less than two-and-a-half pounds, with less than a pound mounted on the helmet itself.
