What is the collar device of a cadet Lieutenant Commander?

The collar device of a cadet Lieutenant Commander is represented by four gold bars. This insignia signifies a specific rank within the cadet program, distinguishing the Lieutenant Commander from other ranks through the number of gold bars worn on the collar. The use of gold bars as a visual identifier for ranks is a standardized practice, making it easier to recognize the hierarchy and roles within the cadet organization.
