I'm not sure what they are actually trying to accomplish, but when I was in back in the mid 80's we didn't typically say "Aviation Boatswains Mate Carroll come here please" Or "First Class Petty Officer Ridgell asked me to chip paint today". It was just Petty Officer Ridgell or Airman Carroll if a rank qualifier even needed to be inserted into the conversation. More often than not it was just the last name.
