Drat it all!
I started looking up S/G-6 to see if I could find out when it began and had no luck so far. I did find that on the Wikipedia entry on staff positions that G stood for "ground" vice "general" as it was a designation for Army and Marine. It also said that was NATO so I don't know.
Oh, well. Perhaps I can try to look back in books and records and find out when the term was first coined.
