What is the collar device of an Ensign?

An Ensign in the U.S. Navy holds the rank of O-1, and their collar device is represented by one gold bar. This insignia symbolizes the entry-level officer rank, which is the starting point for commissioned officers in the Navy. The use of a gold bar as a rank insignia is significant because it differentiates the Ensign from other ranks, providing an immediate visual recognition within the naval hierarchy.

The gold color of the bar is important as it signifies the officer's status and authority, while its singular form indicates that they are at the earliest stage of their career as a naval officer. This insignia marks the transition from enlisted personnel to officers, highlighting the responsibilities that come with the position while still being representative of a junior rank among officers. Understanding the symbols of rank and insignia within the Navy is crucial for navigation, recognition, and respect in military environments.
