AR 600-25 Military Customs and Courtesies Practice Test

When you meet a noncommissioned officer in a formal setting, you show proper respect by using their rank and offering a courteous greeting, following the event’s protocol. This strengthens the chain of command and sets the tone for military decorum. Saying only the last name omits the rank, which diminishes their authority in a formal context. Simply calling someone “Sir” or “Ma’am” is usually reserved for commissioned officers, whereas enlisted leaders are properly addressed by their rank (and, when appropriate, their last name) with a brief greeting like “Good afternoon, Sergeant Smith.” Ignoring the person or proceeding without acknowledgment violates etiquette and duty standards. Following the event protocol ensures you meet the specific expectations for that gathering.
