Re: to make things more (nu)clear
Davy Crockett had a 25t yield IIRC.
It was a tactical nuclear weapon for use as part of a strategic nuclear battle. While Washington and Moscow were covered in radioactive dust and Colorado and Sverdlovsk were seas of glass, Soviet tanks in Germany would be taken out by human-launched tactical nukes.
However, the Russian Federation has actual tactical nukes for use on their own territory against invading armies. NATO won't be allowed to copy Hitler's Blitzkrieg. Russian planners have long memories.
