Just out of curiosity why the use of what I would call a "degree" symbol when enumeration squadron membership. I have noticed it in many places so I am sure it is entirely correct but I am unfamiliar with the nomenclature in this case. How would that symbol be spoken in this context?
That makes sense, but one wonders why use the symbol which is harder to enter on a keyboard than the equivalent "rd", "nd", or "st"? I would guess it is a European thing as I have never seen similar symbology used in US documents.
