I've been thinking about it a lot since last night and when I was at APG I remember people calling it the US army ordnance
and chemical center and school. I could swear it was USAOCC&S but when I searched online I could only find USAOC&S with one "C", not two. Tomorrow is 37 years to the day I got my diploma for small arms repair and it says on it US Army Ordnance Center & School. I just can't believe I was wrong about the name of the place for so many years. Somewhere in my "office" I have a picture of me sitting on the hood of my SUV wearing a school T-shirt but don't think it would have enough resolution to see what it says.
I also looked up some of the MOS's we had in the armament section. If I can remember right from last night 45K which was tank turret repair is something else now and 45L which was artillery repair no longer exists and part of it is now included with 45B. I can't remember what the MOS code for fire control instrument repair or laser/TTS repair were.
MOS 45B AIT USAOC&S APG, MD USA.
