It sounds a like something out of a sci-fi movie, but the US Army has a new toy to play with – a “magic” smart bullet that will float in the air for up to 30 minutes until you come into range before taking you out. An airborne tripwire, of sorts, which you really don’t want to mess with.
Thankfully, even if you do end up tangling with this thing, it might not kill you. It’s part of the Nonlethal Warhead for Miniature Organic Precision Munitions program, and unlike its lethal brother the LMAMS (Lethal Miniature Aerial Munition System) it shouldn’t kill you, in theory. I say shouldn’t because all less-than-lethal bullets can still kill you if they hit you in the head, or you get a bit too close.
The new warhead is designed to hang around at up to 100m in the air after firing for a full 30 minutes, and will target anything that looks human-sized. I get the impression this thing would have been really useful in the London riots last summer – fire off a whole salvo of these beauties and watch all those the mental-underachievers run for the hills.
