New WO1
No, we are not squirming, we are just gobsmacked that anyone (Brit or Septic) could be so up themselves as to ask such a self-obsessed question. In short, I would not give you (personally, not all WOs) the time of day, let alone a salute! Quite frankly, US WOs will be treated by me in exactly the same way as UK WOs; no salute, due respect to the rank and experience, and they will be called "Mr" by officers.
I too have socialised with a CW3 in the Officers' Mess (not Club!!!!) and have found him to be a thoroughly nice guy. However, I my humble opinion, he is still a WO and should not be there; his membership was only down to the dogged insistence of the US Officers on base. The Officers' Mess is for Officers and (the yanks may be a little suprised) we actually have a WO and SNCOs Mess for (you guessed it) the WOs and SNCOs.
As a little aside, Mr Pickle used to be an "other rank" who once went on a trip to the good 'ole US of A. Upon arrival, and being the first one off the Nimrod, I was suprised (as a Senior Aircraftman) to be addressed by a Sergeant First Class (or so it seemed) as "Sir" and asked if I "would like the trash taken off" although I am junior to her by several ranks!! Apart from telling her that the Aircrew could make their own way off, I was a little taken aback. If you don't understand our ranks, how can we be expected to understand yours?
