Which example represents a form of address by duty title?

• A. Commanding Officer
• B. Colonel Smith
• C. Sir
• D. All three forms

Answer: (A)

Addressing by duty title means naming the role the person is performing rather than their name or their rank. Commanding Officer is the form that fits because it designates the specific duty of being in charge of the unit at that moment, independent of who the person is or what their rank is. Colonel Smith uses a rank plus surname, which identifies the person rather than the current role they’re performing. Sir is a general courtesy, not tied to a specific duty. All three forms isn’t correct because not all options are duty titles.
