Interesting. I wonder if that thing could carry a small .22 cal. "pistol" on it. Maybe have a slightly larger version with 1 round to sneak up on some HVT and pop em with it. Of course accuracy would probably be an insult to the drone and it'd probably be smacked to the ground by the time it actually got an aim on someone.
Leave it to 'Mericans to put guns on anything that moves!
