Which of the following ranks is classified as O-8?

The rank classified as O-8 is Rear Admiral (Upper Half). In the military pay grade system, O-8 refers to the ranks of officers in the Navy and Coast Guard, where O represents "officer" and the number indicates the specific grade. The designation of O-8 is reserved for high-ranking officials, reflecting a significant level of responsibility and authority.

A Rear Admiral (Upper Half) typically commands naval operations and has a crucial role in strategic decision-making. This rank is distinguished from other ranks, such as Colonel (O-6), which is an Army, Air Force, or Marine Corps rank, or Lieutenant General (O-9), which indicates a higher rank than O-8. The rank of Admiral (O-10) also exceeds O-8 and represents the highest levels of command in naval service. Understanding these distinctions is crucial for grasping the hierarchy and structure of military ranks.
