6 pound drones called switch blade

"The 2-foot-long Switchblade is so named because its wings fold into the fuselage for transport and spring out after launch. It is designed to fit into a soldier's rucksack and is fired from a mortar-like tube. Once airborne, it begins sending back live video and GPS coordinates to a hand-held control set clutched by the soldier who launched it.

When soldiers identify and lock on a target, they send a command for the drone to nose-dive into it and detonate on impact. Because of the way it operates, the Switchblade has been dubbed the "kamikaze drone."
