If you are at the O-8 level, which of the following ranks do you hold?

At the O-8 level, an individual holds the rank of Rear Admiral (Upper Half). This rank is part of the Navy's commissioned officer ranks and is classified as a two-star admiral. In the military rank hierarchy, O-8 signifies that the officer has progressed to a significant leadership position, typically overseeing large units or significant operational areas.

The other ranks listed do not match the O-8 classification. Brigadier General and Major General are ranks associated with the Army, Air Force, and Marine Corps, categorized as O-7 and O-8 respectively. However, Brigadier General is O-7, while Major General is O-8, which could cause confusion in the context of the Navy. Rear Admiral (Lower Half) corresponds to O-7, thereby not reaching the O-8 level. Therefore, Rear Admiral (Upper Half) correctly aligns with the requirement for the O-8 rank.
