What is the rank insignia of an O-10 in the Marine Corps?

The rank insignia of an O-10 in the Marine Corps is represented by four five-pointed silver stars. This designation reflects the highest possible rank within the Marine Corps, which is that of a General. The use of four stars has a historical significance and differentiates the O-10 rank from lower ranks, which have fewer stars in their insignia.

Such visual representations are vital for identification of rank during military operations and formal events, ensuring immediate recognition of a General’s status.
