What is the proper way to address Army Chaplains?

The proper way to address Army Chaplains is to use "Chaplain" followed by their last name or "Chaplain" and their rank followed by their last name. This form of address respects the established protocols of the military and recognizes the unique role that chaplains play within the Army.

Chaplains have a specific title and rank that reflect their duties and responsibilities, and addressing them in this manner not only shows respect for their position but also acknowledges their authority and the solemnity of their role in providing spiritual support. Using "Chaplain" includes their title which is crucial for maintaining the formality expected in a military context.

The other addressing options do not conform to military etiquette, as addressing by title only lacks the personalization and respect that accompanies the inclusion of the last name. Referring to a chaplain solely by their first name diminishes the formal recognition of their rank and position, while addressing them by their last name alone is incomplete and lacks the necessary title, which is important in a professional military setting.
