The O-4 rank corresponds to which title?

The O-4 rank corresponds to which title?

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

Answer: (C)

Understanding officer ranks by pay grade helps you map titles to the level of responsibility. O-4 is the fourth officer pay grade, and in the Army, Air Force, and Marine Corps the title at that level is Major. This sits between Captain (O-3) and Lieutenant Colonel (O-5), reflecting a step up in leadership and staff duties as officers take on larger commands and more complex responsibilities. Note that in the Navy, the same O-4 pay grade is called Lieutenant Commander, so the exact title can vary by service. For the Army/Air Force/Marine Corps context, Major is the correct match for O-4.
