[quote]The Davy Crockett was a recoilless rifle fitted with a nuclear warhead and was fielded in the late 1950s into the 1960s by the US Army. There was also debate on whether or not to equip the West German military with the system, but the idea was rejected out of concern that it would reduce NATO's ability to respond to military action without resorting to nuclear warfare.[/quote]
