ok so I just joined up and it sucks but i cant ask and nobody seems to be telling me, so basically my question is: When do I salute an officer, and how do I recognize who to do this to? I get that I brace up to all officers, but is it just an officer in a command role (OC, CO?) that I would salute? And if I've heard an officer some times get reffered to as Mr Smith. Is that how a soldier should refer to them, or should it be Captain Smith? cheers!
