Steve's documents fail yet again. Steve's confusion is understandable. The following is from the USMC MOS Manual from 1945. The Scout-Sniper MOS was 8541 prior to this manual, as the Marines used Army MOS numbers, and 317 prior to that. As one can see, the official title was Scout Sniper, not Scout as Steve mistakenly suggests.

Documents are nice, if you know the origin and context. Steve posted a heavily cropped document, as he typically does; but I don't see USMC or Marines or anything else that indicates the origin of that snippet of an unknown document.
