Atomic Annie, the gun you refer too was the first atomic cannon in the US inventory. It was a 240mm gun. The main problem with the Davy Crockett nuke was that the inner radius of danger was greater than the range of the system. Both were early 1950s systems

Later improved systems: 155mm Self-propelled gun-howitzers (M-109 series) put nukes out to 16+ kilometers, the 8inch (M-110) guns (vice howitzers) had a longer range. Both shells made the occupants of a grid square and their neighbors evaporated critters. I served in the Fire Direction Center (FDC) of M-109 units in the States and Germany. We trained constantly in figuring the firing data for nukes.

The only thing I ever had to do with nukes was being in the Regimental S3 shop when a FIREBREAK Emergency Action Message would come in and the fire support element would have to decode it. Horns went off and whoopee lights flashed and it was all very Dr. Strangelovian

This was back when Brezhnev, Chernyenko and Andropov were taking turns catching cold and dropping out of sight and then being announced to have died. We got lucky things turned out as well as they did. Could have been real bad.
