Which rank insignia has four five-point silver stars?

The insignia that features four five-point silver stars represents the O-10 rank, which is typically the rank of a four-star general or admiral in the military. This rank is the highest in the standard officer ranks and is associated with significant leadership responsibility and command authority.

In contrast, lower ranks such as O-8 and O-9 have fewer stars; O-8 is represented by a two-star insignia and O-9 by a three-star insignia. The O-6 rank, which is a colonel in the Army, Marine Corps, and Air Force or a captain in the Navy, uses a silver eagle insignia, reflecting its lower rank compared to O-10. Therefore, the presence of four stars distinctly identifies the O-10 rank insignia, denoting the highest level of officer rank within the military hierarchy.
