An interesting Salon.com article about friendly fire, by David Morris. I don't understand how $180 Million wasn't enough to create and deploy an anti-fratricide system. In this age of encryption and GPS technology, it seems like outfitting every soldier with an encrypted GPS communicator that only the Air Force can read would be a fairly cheap and simple way of revealing their positions to our bombers and only our bombers. You could hook it up to their heart beat so that it would be useless if they were killed. People buy GPS watches for their kids. How much could this possibly cost per soldier?
