How many gold stripes make up the shoulder device of an O-4 in the Navy?

The shoulder device for an O-4 (which is a Commander in the Navy) features two half-inch gold stripes placed in parallel, with a quarter-inch gold stripe in between them. This design symbolizes the rank of Commander, distinguishing it clearly from other officer ranks. Each stripe represents a certain level of authority and accomplishment in the Navy, and the inclusion of the quarter-inch stripe adds a unique element to the shoulder device that specifically identifies the O-4 rank. This specific arrangement ensures clarity in rank recognition, which is critical in military settings.
