Bert - I think i was not clear enough in what I was having you do. This is an example of what I once did when I wanted to learn about my husband's MOS. I ordered this manual which I found listed in the BSIR, "Classification of Officers - Commissioned and Warrant." It contained a description with the code #s of all the MOS of officers and warrant officers. And the things the person becoming or performing the MOS was required to know and how he could acquire that knowledge.
I wasn't looking for enlisted men but surely there must have been something similar. Mary
