How many MEFs exist and what are their designations?

• A. I MEF, II MEF — two MEFs.
• B. I MEF, II MEF, III MEF — three MEFs.
• C. I MEF, II MEF, III MEF, IV MEF — four MEFs.
• D. I MEF only — one MEF.

Answer: (B)

There are four Marine Expeditionary Forces. They are named I MEF, II MEF, III MEF, and IV MEF, giving the Marine Corps four separate, forward-deployed, combined-arms formations that can operate independently or as part of joint task forces. This four-fold structure ensures global reach and rapid response to crises around the world. The other options suggest fewer MEFs, which would leave gaps in coverage and readiness, so the four-MEF designation is the correct and complete answer.
