Which rank is classified under pay grade O-2?

The rank classified under pay grade O-2 is Ensign. In the military rank structure, each rank is associated with a specific pay grade, which determines the pay and responsibilities of the personnel holding that rank.

At O-2, the Ensign rank has a crucial role, especially within the Navy, where it signifies a newly commissioned officer who has just completed their training. This position is typically the first official rank an individual achieves after completing their commissioning program, marking a transition from cadet status to a full-fledged officer.

The other ranks listed correspond to higher pay grades: Lieutenant Junior Grade (O-1) is a step above Ensign, while Lieutenant (O-3) and Lieutenant Commander (O-4) are further up the hierarchy, indicating increased responsibility, experience, and authority. Understanding these ranks and their associated pay grades is essential for comprehension of military structure and the progression of an officer's career.
