Which rank is O-6 in the United States Marine Corps?

• A. Major
• B. Colonel
• C. Lieutenant Colonel
• D. Brigadier General

Answer: (B)

O-6 corresponds to the rank of Colonel in the United States Marine Corps. Officer ranks use the O-scale, and the sequence around this level goes Major (O-4), Lieutenant Colonel (O-5), Colonel (O-6), then Brigadier General (O-7). So the rank that matches pay grade O-6 is Colonel. This is a senior, field-grade officer who typically commands a regiment or serves in a high-level staff role. The other options map to different pay grades (Major is O-4, Lieutenant Colonel is O-5, Brigadier General is O-7), so they do not match O-6.
