Which rank corresponds to an O-5 in the Navy?

The rank that corresponds to an O-5 in the Navy is Commander. This rank is a part of the officer classification system where the "O" indicates that it is an officer grade, and the "5" denotes its level within that system. In the Navy, Commanders serve crucial roles such as commanding smaller ships, units, or shore installations and often have significant leadership responsibilities.

Understanding the hierarchy of Navy ranks is important for navigating military structure and protocol. For instance, the rank of Captain is an O-6, which means it is one level higher than a Commander. Lieutenant corresponds to O-3, and Lieutenant Junior Grade is an O-2, both of which are lower ranks. This distinction in ranks is vital for understanding command authority and organizational structure within the Navy.
