What is the minimum rank of the president of the E-7 selection board?

The minimum rank for the president of an E-7 selection board is the rank of Captain. This is established to ensure that the board is led by an officer with a significant level of experience and authority, which is crucial in making decisions regarding promotions to the E-7 pay grade.

By designating the president as a Captain, the Navy ensures that there is a capable leader who has a solid understanding of the qualifications and expectations for the E-7 rank. Captains have typically served in various leadership roles and possess the experience necessary to guide the selection process fairly and effectively. Additionally, this rank reflects a level of responsibility that aligns with the important duties of assessing potential candidates for advancement.

The other ranks mentioned do not meet the minimum requirement for presiding over the selection board and would not possess the same level of operational experience or leadership stature that a Captain would.
