Anti-drone gun takes down targets from 1.2 miles away

There are numerous systems built to take down wayward or dangerous drones, but they tend to have one big catch: you need to be relatively close to the drone, which could be scary if the robotic aircraft is packing explosives. DroneShield thinks it can help. Like most rivals, it doesn't destroy the target drone -- it just forces the vehicle to land or return to its starting point. Anti-drone teams can not only disable threats from a safe distance, but potentially locate their pilots. It's not the lightest machine at about 13 pounds, but it's portable enough to be usable by one person. You don't need technical training, either, so it's easy for security staff to use.
