What is the shoulder insignia for a Lieutenant Commander (O-4)?

The shoulder insignia for a Lieutenant Commander (O-4) in the U.S. Navy is represented by a gold oak leaf. This insignia signifies a rank level that is typically associated with leadership roles within various operational contexts.

The gold oak leaf designates the specific rank of Lieutenant Commander, distinguishing it from other ranks. The insignia allows for immediate recognition of the officer’s position and experience level by both peers and subordinates. Understanding these insignia is crucial for maintaining proper military decorum and facilitating effective communication within command structures.

The choices that are designated for other ranks contribute to possible confusion but serve to illustrate the unique characteristics of each rank. For instance, the one silver oak leaf is associated with Commander (O-5), while two silver stars denote a Rear Admiral (Upper Half), and one gold star is reserved for specific distinctions, such as indicating a service award or subsequent promotions. Thus, the gold oak leaf serves as a clear and recognized symbol of the rank of Lieutenant Commander.
