A helmet-mounted radar unit seems redundant with the kind of crazy surveillance and intel they already have available or in the pipes, but hey, whatever helps our boys. While satellite and air-based imaging are invaluable to the modern field commander, an individual infantryman has little feedback in an more local tactical situation. So why not have an imaging system for individuals?
The Helmet Mounted Radar System (HMRS) is “a miniature, low power, near 360-degree field of view Moving Target Indicator (MTI) radar sensor that will alert the soldier to the whereabouts of a target out to at least 25 meters.” 25m isn’t very far, but providing even a hint of a nearby enemy could be the difference between life and death. The only trouble, it seems to me, is that the modern soldier is going to be so weighed down with all the gadgets and armor made to save his life that he won’t be able to maneuver.
Not to mention, this may lead to extremely scary moments like that part in Alien where the guy is in the tunnels and IT’S RIGHT BEHIND YOU AAAAAARGH
