Hmm. I hadn’t heard that before. We (the US) haven’t had Marine ground units at/near the DNZ for many moon’s. Additionally, the logistics of storing/handling/deploying such weapons (if they existed) would have been extremely expensive, not to mention politically sensitive.
Regards,
I don’t know if they were ever deployed to the DMZ, but SADMs (Special Atomic Demolition Munitions) definitely exist or existed. I have no idea what their status is currently.
I did hear an anecdote somewhere from a soldier who’d been on the DMZ of a big ration can full of food or coffee or something being delivered to an outpost that was known to be observed by the North Koreans. A great show was made of handling the can with deadly-serious care and under heavy, steely-eyed guard. A few days later, broadcasts out of the North accused the US Army of deploying man-portable nuclear devices to the DMZ. I hope the chow or whatever was good.
