Photos: Gung-ho gadgets for U.S. troops

The Tacmav, or tactical mini air vehicle, is one of a number of devices being developed by the U.S. Army's Rapid Equipping Force. The unit purchased the model plane commercially and modified its software. Its mission: to carry a camera to let soldiers in the field check over the next ridge or around the corner.
