Who we are

III MEF is the nucleus of a joint and coalition Stand-In Force within the First Island Chain. In competition, III MEF assures and expands access for the joint force across the Indo-Pacific. In crisis, it provides in-place response forces to secure allies and partners while deterring adversary aggression. In conflict, III MEF fights from advanced naval bases as part of a naval expeditionary force and enables Joint Force objectives in the Indo-Pacific.
