Which rank corresponds to the O-2 pay grade?

The rank that corresponds to the O-2 pay grade is Lieutenant Junior Grade. In the United States Navy, the officer ranks are structured in a hierarchy, and the O-2 pay grade specifically designates the position just above the O-1 pay grade, which is Ensign.

Lieutenant Junior Grade is the entry-level rank for officers who have been promoted from Ensign after completing the necessary time in service and meeting specific qualifications. This rank signifies a progression in an officer's career, reflecting increased responsibility and experience.

Ultimately, knowing this ranking structure is crucial for understanding the military hierarchy, as each rank carries specific roles, responsibilities, and levels of authority within the Navy.
