What is the shoulder device of an O-3 in the Navy?

The shoulder device for an O-3, which is the rank of a lieutenant in the Navy, is represented by two half-inch gold stripes. This insignia indicates the officer's rank and is worn on the uniform to signify their position within the Navy hierarchy. The design of the insignia follows a clearly defined structure, with each rank having a distinct number of stripes that denote the officer's level of experience and responsibility.

This specific design of two half-inch gold stripes is consistent across the U.S. Navy, providing a standardized way to identify ranks among officers. Drawing attention to the other options, it's clear they represent different ranks or combinations not associated with an O-3. Understanding these insignias is crucial for recognizing the rank structure and the roles of personnel within the Navy.
