The US Navy ships clerk shoulder board with two and a half bars pair represents a hypothetical rank between Lieutenant Junior Grade and Lieutenant. The shoulder board is rectangular in shape, typically featuring a dark navy blue background. Across the background, two and a half gold-colored bars run horizontally. This unique configuration symbolizes a rank positioned between Lieutenant Junior Grade and Lieutenant, indicating a significant level of authority and responsibility within the Navy's officer ranks. These shoulder boards are worn on the uniform jacket or shirt of the officer, placed on each shoulder to display their specialized rank and role within the Navy, potentially in a position such as a Ships Clerk.
