I thought the Micro Air Vehicles would be small hovering robots, but according to this video from the Air Force Research Laboratory, they will be more like robotic birds with spy and attack capabilities, capable of blending with the environment.

Not only these things would be able to position themselves to perform long-term surveillance duties, but they would be enable to engage enemies individually, attacking humans with incapacitation chemicals and even explosives. The future is going to be a lot of fun. [Design World Online]
