How many silver stars are associated with the rank of Rear Admiral (O-8)?

The rank of Rear Admiral (O-8) in the U.S. Navy is designated by two silver stars. This insignia represents the officer's rank and signifies their position within the naval hierarchy. Each star increases in rank with the significance and responsibilities of the positions held. The silver star specifically indicates the level of Rear Admiral compared to other ranks in the Navy and is part of the larger system of ranks where increasingly higher numbers of stars denote higher ranks.

In context, it is important to note that other ranks have differing insignias which include fewer or more stars. For example, the rank of Commodore is often denoted with one star, while the rank of Vice Admiral is associated with three stars, and Admiral typically includes four stars. Such distinctions help to clearly identify the rank and level of authority each officer holds within the Navy's structure.
