British Army Using Tiny Drones for Surveillance

The Black Hornet Nano Unmanned Air Vehicle is 4 inches long

British troops are using a nano drone just 10cm long and weighing 16 grams on the front line in Afghanistan to provide vital information on the ground.

They are the first to use the state-of-the-art handheld tiny surveillance helicopters, which relay reliable full motion video and still images back to the devices' handlers in the battlefield.
