What is the shoulder device of an O-2 in the Navy?

In the Navy, the shoulder device of an O-2, which is the rank of Lieutenant Junior Grade, is represented by a gold stripe configuration that includes one half inch gold stripe with one quarter inch gold stripe above it. This specific arrangement symbolizes the rank and is important for identification within the Navy's rank structure.

The gold stripes denote the officer's rank progression, with a larger stripe indicating the primary rank and the additional smaller stripe reflecting their advancement to the Lieutenant Junior Grade position. This visual representation is crucial for maintaining the structure and order within military ranks, allowing personnel to easily recognize the hierarchy and competency levels of service members.
