M65. Recoilless. Nuclear. Rifle. I guess that's really all I have to say.
Hey, wait! Before you run off into the yard to test this puppy out, there are some things you might want to consider. Firing off your own 0.1 kiloton warhead from a 155mm recoilless rifle nicknamed the "Davey Crockett" might sound like a whole lot of fun, but what are you going to do after? You know, when said warhead blows up? With a range of only three miles, even a gentle wind will blow fallout your way. Luckily, the M65 never saw any action beyond a few tests in the '60s.
