Which of the following is the O-10 rank in the Navy?

The O-10 rank in the Navy is designated as Admiral. This rank represents one of the highest officer ranks in the Navy, typically commanding significant naval operations and overseeing multiple subordinate units or fleets. The Admiral rank is involved in strategic decision-making at the highest levels of naval command and serves on the highest echelons of military leadership.

While a Fleet Admiral is also a high-ranking position, it is a five-star rank, which is not regularly used in contemporary contexts and is considered a special rank that can only be awarded in times of war. The other ranks listed, Vice Admiral and Rear Admiral Upper Half, are O-9 and O-8, respectively, which are lower than the O-10 rank of Admiral. Understanding these distinctions is crucial for grasping the hierarchy and structure of naval ranks.
