au contraire nuclear artillary was always one of Robert Oppenheimer's nuttier ideas.

Position nuclear weapons where they can be overrun by an advancing Warpac force. Second worst idea ever. (The Davy Crockett nuclear bazooka beats it)

Exactly.

Nuclear artillery operated under the same release constraints as strategic and theater weapons. Those release constraints were completely incompatible with the timeline for an artillery fire mission.

BTW, there is supposedly a film of a Davy Crockett being fired to maximum ballistic range from a jeep...which then gets blown a$$ over teakettle by the blast. Yeah, that was pretty stupid.
