What is the shoulder device of an O-5 in the Navy?

In the Navy, the rank of O-5 corresponds to a Commander. The shoulder device for this rank is accurately represented by three half-inch gold stripes. Each stripe symbolizes the rank and experience of the officer, with the three stripes indicating the position of Commander, which is a senior field officer role. This insignia is important for visual identification of ranks among military personnel, enabling quick recognition during operations and formal events.

The other choices do not represent the correct insignia for a Commander; for example, one half-inch gold stripe signifies a Lieutenant, while two half-inch gold stripes represent a Lieutenant Commander. Four half-inch gold stripes are used for Captain (O-6), which is a rank above Commander. Thus, the correct identification of the shoulder device is essential for understanding naval hierarchy and rank structure.
