XM29 Davy Crockett X3

Tactical nuclear recoilless rifle, deployed in Western Europe in the late 1950's the idea was to take out Soviet troops and tanks with a small nuclear detonation. As impressive as a one man nuclear war sounds there were noticeable drawbacks to the Davy Crockett, namely that the fallout radius is smaller than the firing range. This means that firing the Davy Crockett will expose the gunner to unhealthy levels of radiation making it a desperate last ditch weapon at best.
