Military Occupation Specialty Codes

Dear Friends,
The world is complicated, Militiary Occupation Specialty Codes reflect this complexity.
All of the below is way beyond my "organizational ability".
Good Luck to us all

The Nike Hercules MOS 24U prior to 1985 was more than just Custodial Mechanic. In the 70's and early 80's the MOS name was a Nike Hercules Electronic Mechanic. The coarse length was 32 weeks long and covered the hole Missile, test equipment, LCI, SSG, Launcher and ECS. Basically the entire launching area.

I worked at the school house from 82 to 85 and we were still teaching the entire course. It was after 85 that they shortened the course to just warhead training and turned it into a custodial only MOS, and then closed the school some time in 88 I believe.

On your MOS info pages you give some information on occupation codes. Attached you will find some additional information related to foreign occupation codes.

After my training on Fort Bliss I worked a couple years (1969-1972) as a radar/computer (electronic) technician on an IFC of the Netherlands Airforce in Germany. Looking at the training chart my occupation was “4B-222BX/121-226.1X”. Based on some examination results forms, I followed the 24Q20X course. Normally they referred as '226' to the IFC technician. I am not sure if this reference is also used on US-sites.

The attached charts are from a Fort Bliss information pamphlet “Foreign Student Program”. If you are interested in this document (16 pages) for your archive I can sent you a scan.

David Novak pointed out Vietnam-era MOS codes: Army
and adds
Looks like by the copy of orders I have kept, MOS designations from nnn.n to a 5 digit alphanumeric one occurred somewhere late 1965 to early 1966. During that period I went from a 229.1 to 26J20, ABAR mechanic. Don't remember much about the change other than remembering the designations

On ed thelen's website you listed both 16k and 17h as "fire distribution crewman". It was changed from 17h to 16k during the months of February/March, 1968. I entered the service with the guarantee to be a 17h. While in basic, I was told the MOS no longer existed and the major at Ft. Campbell said I could be a 16h. So, instead of going for on-the-job training (ojt) for 17h in Mpls/St Paul, when I finished basic i was sent to Ft. Bliss for advanced individual training (ait) for 16h.

When I arrived at Ft. Bliss, the officer overseeing the operation saw what had happened to me and had me on a plane for Mpls/St Paul for ojt training in 16k. Seems they had to get me there within 36 hours after basic or I could have got out on "breach-of-contract". I arrived at the site in Mpls/St Paul 34 hours after basic. They said there was an ait school at Ft. Bliss, but the only 16k's I ever met were all ojt.
