Wired.com carries a gee-whiz tale from the Office of Naval Research on development of an army of drones that would fight the battles of tomorrow. It all sounds very Star Wars — and expensive. But the notion is that human commanders at the top would provide goals that a network of unmanned but highly-networked machines would work to achieve. That could be taking a hill in a combat zone, capturing a known enemy, or helping rescue disaster victims. One wonders who such an army would fight (the Chinese army of 2020? A resurgent Russia?) But maybe this will be one of those ideas that die on the vine in the armed services but find a robust future in the private sector. The original technology, after all, came from drones built to track migrating whales.
