I’ve always been a big fan or rifles. The bigger the better. But somehow I think the military got it right and decided that this particular rifle was just a little too big.

This 155mm bad boy fires a 0.1 kiloton nuclear, equal to about 10 tons of TNT, warhead about 3 miles down range. Not quite far enough to get it beyond the kill zone for the lucky guy that pulled the trigger. Nicknamed the Davey Crocket, it fortunately never saw action beyond a few test shots in 1962.
