What does the shoulder device of an O-8 in the Navy feature?

An O-8 in the Navy refers to the rank of a Rear Admiral, Upper Half. The shoulder device for this rank is characterized by the presence of two five-point silver stars. This distinctive feature signifies the authority and status associated with the Rear Admiral, Upper Half rank, differentiating it from ranks below it.

The inclusion of two silver stars is critical in the visual identification of the officer's rank, aligning with the Navy's system of insignia where the number of stars corresponds to the officer's level of command. Thus, the correct identification of this insignia is essential for proper recognition within military and official contexts.

In contrast, the other choices—individual stars or stripes—do not align with the rank of O-8, as they represent either lower ranks or different insignia altogether.
