Marine Corps O-3 corresponds to which rank?

Marine Corps O-3 corresponds to which rank?

• A. Captain
• B. Major
• C. Lieutenant
• D. Colonel

Answer: (A)

In the Marine Corps, officer ranks follow a pay-grade system from O-1 to O-10, where the number after the O increases with seniority. The pay grade O-3 corresponds to the rank Captain. That makes Captain the correct match for this level. For context, Major is the next level up (O-4), Lieutenant is one level below (O-2), and Colonel is higher still (O-6). A Captain is a mid-level officer who often serves in roles such as commanding a company, which helps anchor why this rank sits at O-3.
