Which statement accurately describes the role of SES/GS civilians in ceremonial duties?

The statement that SES/GS civilians may not act as the presiding officer for ceremonies correctly reflects the established protocols regarding their roles in ceremonial duties. In military and official ceremonies, there are specific guidelines governing who is authorized to preside over such events. Generally, the presiding officer must hold a certain rank or position that is recognized within the military hierarchy, and SES/GS civilians do not typically meet this requirement.

This distinction underscores the importance of maintaining proper military decorum and hierarchical structure during ceremonies. While SES/GS civilians may participate in ceremonies in other capacities and fulfill various roles, their inability to preside over these events helps ensure that ceremonies are led by individuals who have the authority linked to their military rank or official capacity. Thus, the proper order and tradition of military functions are upheld.
