I have googled and used search on the forums and came up with nothing. How do you address non commissioned ranks in the RN? I was an Army Cadet as a kid and still remember the common sense stuff. Officers And WO's as Sir or Mam ect. No idea on NCO or other ranks. I assume I will be instructed quickly at my PRNC and Raleigh on this. Prob best not to lead with "here! Bigman! Whats you name?".
