Fuck it I'm saying it again.

If you're referring to an officer and it's not to his face. Don't say "The Sir". You sound like an absolute idiot. "Hey the sir said xyz". Just say "the lieutenant" said whatever. Saying "The sir" makes you sound so stupid. What "Sir" said that? The Lieutenant, the Commandant of the Marine Corps, the Major???? Which "SIR" are you talking about!? Say the fucking rank when not directly speaking to the individual.

Edit: Marines! Holy shit pay attention. Did you know you can actually call an officer by their rank? Also when not directly talking to them you can call them by their rank.

EXAMPLE A: A bunch of officers in one room. How do I get one of their attention? "Excuse me Lieutenant "whoever" Sir may I speak with you".

EXAMPLE B: Lieutenant "whoever" said to be at the armory at 0400
