What is true regarding enlisted members officiating a promotion ceremony?

The notion that no enlisted member may officiate a promotion ceremony reflects the traditional practice and regulations within the military context, which typically reserve such ceremonies for commissioned officers. This ensures that the ceremony upholds a certain level of formality and respect that is often associated with ranks and responsibilities. Commanders and higher-ranking officers are generally seen as the appropriate figures to conduct ceremonies that acknowledge and formally promote individuals within the ranks, as this aligns with the hierarchy and structure of military operations.

In contrast, other options suggest possibilities that may not align with formal protocols in military tradition. Allowing enlisted members to officiate could undermine the established chain of command. Although enlisted members certainly play important roles during promotion ceremonies—such as being invited attendees or assisting—officiating is typically left to those who hold a commission and carry the authority that comes with it.
