What is the rank for O-5?

The rank of O-5 corresponds to the position of Commander in the U.S. military rank structure. In the Navy, the rank of Commander is a company-grade officer rank that typically commands a ship or a submarine, leads a squadron, or holds other significant leadership positions within maritime operations.

Understanding military ranks is crucial, as they denote levels of responsibility and authority within the armed forces. The rank of O-5 is positioned above O-4 (which is Lieutenant Commander) and below O-6, which is Captain.

The other ranks listed—Rear Admiral Upper Half, Vice Admiral, and Admiral—are all higher ranks (O-7 and above) within the Navy, representing higher levels of authority and command responsibilities. Thus, the correct identification of O-5 as Commander underscores the hierarchical structure and ranks in the military.
