What is the sleeve device configuration for an O-6 in the Navy?

In the Navy, the sleeve device configuration for an O-6, which is the rank of Captain, is specified as four half-inch gold stripes on the dress uniform. This configuration reflects the officer's rank and distinguishes them from those of lower ranks. Each of the half-inch stripes represents a level of responsibility and status within the naval hierarchy. The importance of this insignia lies not just in identification but also in the authority it conveys within the naval command structure.

Having four half-inch gold stripes signifies that the individual has far more experience and responsibility than junior officers. This reinforces the structure and discipline that is fundamental to military operations, ensuring that rank and command are immediately recognizable.
