Which rank corresponds to Navy O-2?

The rank that corresponds to Navy O-2 is Lieutenant Junior Grade (LTJG). In the Navy's ranking system, O-2 designates the second officer rank, which is achieved after serving a period as an Ensign (O-1).

Lieutenant Junior Grade is instrumental in the organization as they carry out duties similar to those of their senior officers but may have less experience and responsibility. This rank involves working under the guidance of a more senior Lieutenant (O-3) and often leading junior personnel or being in charge of smaller units or sections within a larger organization.

The other ranks listed do not match the O-2 designation: Ensign (O-1) is the entry-level officer rank, while Chief Warrant Officer Four (CWO4) and Chief Warrant Officer Five (CWO5) are higher ranks, specifically in the warrant officer category, designated as O-4 and O-5 respectively. This reinforces the classification structure of officer ranks in the Navy and highlights the progression from Ensign to Lieutenant Junior Grade.
