Wifi gunsights that tell your smart goggles where to aim. Artificial intelligence that tells distant artillery batteries whenever you spot a high-priority target. Backpack transmitters, remotely controlled by technicians miles away, that jam enemy communications while you focus on the fight. A jamming-resistant GPS that double-checks your location against a wearable inertial navigation system and pedometers in your boots. These are all technologies the Army is now developing or, in some cases, fielding in a few months.
The American grunt has gotten ever more high-tech since 2001. Handheld GPS, tactical radios, night vision goggles, electronic gunsights, and more have accumulated to the point where the weight of batteries has become a major burden.
