While the US military continues to develop new and awesome ways of blowing aerial drones to smithereens, not many of these systems can easily be adapted to use in the civilian realm. That’s why Battelle has developed the DroneDefender, a shoulder-mounted rifle that knocks UAVs offline with a barrage of radio waves.

"It can help us in numerous settings, from the White House lawn to bases and embassies overseas; from prisons and schools to historic sites,"Alex Morrow, technical director on the project, said in a statement. "It easily and reliably neutralizes the threat." The weapon weighs roughly 10 pounds and can target drones up to 400 meters away. When the trigger is pulled, the gun emits a blast of electromagnetic energy tuned to the most common GPS and ISM frequencies, safely disabling the drone and preventing it from accepting any additional commands from its operator. This is especially helpful if the drone is equipped with an improvised explosive device.
