Clarify he's Navy 

I think it would be useful to clarify for the Article that he's a member of the Navy, since the vast majority of people seem to think he's in the Marines.

I know for a fact that it is mentioned a few times that the Spartans are under the jurisdiction of the Office of Naval Intelligence, but does anyone have quotes from either the game or the books to directly back it up? I can't remember exactly were I first head the ONI being in charge.
