So I just learned this about my uncle (mom's BIL) this past weekend.
Apparently when he was in the Army in the mid-to-late 60's he was assigned to some sort of nuclear artillery unit station out at Ft. Sill I believe. He spent 18 months, 10 hours a day assembling, disassembling and reassembling the nuclear shells and innards. They were test in the dark, blind folded, in heavy smoke, etc. and then suddenly were pulled off and that was the end of it. Not sure if them being pulled off coincided with the end of the Vietnam War or not.
My first thought was Atomic Annie, the M65, but from what I can read on the interwebs that was taken out of service in 1963. Anyone have any other ideas?
Oh, and all this came up because he is now having serious health issues which the docs think can be traced to his exposure during this period.
Maybe I should talk to my B-I-L. He was in a unit attached to the 82 airborn, but not acctually part of it. They where the only unit in the world to air drop the M114 155mm. I do recall his mention of Nuke ammo, I just dont remember in what context it was.
I'd tell you but then I'd have to ... well ...
Friend of mine when he was in the Army reserve he was attached to an arty unit with the nuke shells complete with the black circle on the side that read place demo charge here. This was before he went 4 years active in the Navy, then inactive reserve while he was in school and now has been on the active Navy reserve list for several years including 3 or 4 two week paid vacations to Spain a year.
Thanks guys, I'll have to do some more asking of my uncle but he is a bit sensitive about talking about it. In fact he refuses to go to the Veteran's Hospital because he feels the free care (and along with it the possibly better insight into his specific situation) should only be used by those who were injured in actual fighting.... 
In the early 90's, my detachment moved to a building which had been a maintenance facility for such rounds. The site was secluded, far from the flagpole, and secure. Overhead cranes, truck dock, chainlink and concertina, secure entry, etc. Easy access to some nice woods for training. I don't think most of the battalion staff knew where we were. The battaion commander seldom dropped by - too much effort.
Ahh, those were the days.
But, all things must come to an end. On the way to my outgoing change-of-command ceremony, a suicidal doe jumped in front of my Shelby Charger, killing herself and inflicting mortal wounds on the '84. Banged hell out of my car and became a staff weinie on the same day.
