This tiny drone can be carried and deployed by soldiers

Drone-maker AeroVironment has developed a handheld quadcopter that it says can be carried by soldiers on the battlefield and quickly deployed to get an aerial look at a potentially hostile location. The drone, called Snipe Nano Quad, has retractable rotor arms so it can be carried in a compact form and unpacked when needed. It weighs just 140 grams (5 ounces). It's equipped with cameras that can send a visible or infrared image back to a handheld controller unit. The infrared view provides a way to see the body heat of a person who may be hidden. The drone has a top speed of around 20 miles per hour and a radio range of about 1 kilometer.
