How do you properly address a chaplain?

Answer 1

The chaplain in the US Military is considered a dual role person. When the chaplain is in uniform but not in a church or performing a religious duty it is customary to address them as an officer (ie using his rank as a title/name). When the chaplain is performing a religious duty or in the church it is customary to refer to them by their religious title: father (catholic); Rabbi (Jewish); Minister or pastor (Protestant). When the chaplain is out of uniform and not performing religious duties it is customary to refer to him by name (or religious title).
