Occasionally, things that are deadly serious in the real world can sound more than a little silly on paper. An example, to my mind at least, are the proposed robotic urban combat drones being developed for the USAF. Why? Because apparently they will look like frisbees – armed and armoured frisbees, sure, but still remarkably like that thing your dog loves to grab out of the air. The drones will have pretty serious capabilities despite their comedy stylings, and will be tele-operated by soldiers on the ground as they hunt down insurgents.
