USAI has undergone a lot of reconstruction with the advent of digital comm. I was 05H - morse intercept. That MOS is no more; its task has now been merged into 98G which is (oddly) linguist or voice intercept. By the early 80's, the shift was just beginning to occur. Huge operations, such as the Field Station I was at, are now shut down and abandoned. Kinda sad to look at if you were part of any of those.
