At 2 ft. in length and weighing 6 lb. (60 cm, 2.7 kg), the Switchblade drone can be carried into battle in a backpack.
It’s a kamikaze: the person controlling it uses a real-time video feed from the drone to crash it into a precise target—say, a sniper.
Its tiny warhead detonates on impact. In effect, it makes fighters in the field their own air support.
