What rank is denoted by the abbreviation O-10?

The rank denoted by the abbreviation O-10 is Admiral. This designation is part of the military pay grade system, where "O" stands for "officer," and the number "10" indicates the highest level of rank for commissioned officers in naval forces. An Admiral typically commands fleets or large naval organizations, representing a significant level of authority and responsibility.

In contrast to other ranks, Captain refers to O-6, Commander is O-5, and Lieutenant Colonel is associated with the Army and Marine Corps at O-5, while also used for line officers in those branches but is not relevant in this context for a naval rank. Understanding these rank structures is essential for cadets as they help navigate military hierarchy and decode communication within the naval context.
