II MEF
II Marine Expeditionary Force is a principal warfighting organization of the United States Marine Corps based at Marine Corps Base Camp Lejeune, tasked with expeditionary, amphibious, contingency, and joint forcible-entry operations. It provides command and control for combined-arms formations capable of integrated air-ground logistics, working with United States European Command, United States Central Command, and United States Africa Command elements. II MEF routinely trains with allied and partner forces including NATO, United Kingdom Armed Forces, Royal Netherlands Navy, Canadian Armed Forces, and German Bundeswehr for crisis response and power projection.
Overview
II MEF functions as a Marine Air-Ground Task Force headquarters, coordinating a ground combat element, an aviation combat element, and a logistics combat element drawn from subordinate commands such as 2nd Marine Division, 2nd Marine Aircraft Wing, and 2nd Marine Logistics Group. It executes expeditionary operations across littoral regions alongside naval forces like U.S. Sixth Fleet and U.S. Second Fleet, and interoperates with joint organizations such as U.S. Special Operations Command and U.S. Transportation Command. II MEF also supports civil authorities during domestic crises in concert with Federal Emergency Management Agency and North Carolina National Guard elements.
History
II MEF traces its roots to post‑World War II reorganization of United States Marine Corps forces and the establishment of force-level expeditionary headquarters in the Cold War era. Elements of the command participated in contingency deployments during the Cuban Missile Crisis, operations in the Caribbean, responses to crises in Haiti and Dominican Republic, and support to Operation Urgent Fury in Grenada. During the 1990s, II MEF contingents supported Operation Desert Shield, Operation Desert Storm, and humanitarian missions to Somalia and Hurricane Katrina relief. In the 21st century, II MEF units played roles in Operation Enduring Freedom and Operation Iraqi Freedom, while also engaging in multinational exercises such as Operation Bold Alligator, Exercise Trident Juncture, and Exercise African Lion.
Organization and Units
II MEF is organized to generate a tailored Marine Air-Ground Task Force by assembling forces from its principal subordinate commands: the 2nd Marine Division (ground combat), the 2nd Marine Aircraft Wing (aviation combat), and the 2nd Marine Logistics Group (logistics combat). Support and command elements include the II Marine Expeditionary Force Information Group and specialized units collaborating with Marine Corps Forces Reserve and Marine Corps Warfighting Laboratory. II MEF routinely embeds Marine Expeditionary Units such as the 22nd MEU, 24th MEU, and 26th MEU for forward-deployed amphibious readiness. It also coordinates with Navy amphibious ships like USS Wasp (LHD-1), USS Bataan (LHD-5), and USS Iwo Jima (LHD-7).
Operations and Engagements
II MEF and its subordinate units have conducted amphibious assaults, stability operations, maritime security, noncombatant evacuation operations, and humanitarian assistance/disaster relief. Notable operations include expeditionary launches in support of Operation Urgent Fury, air-ground operations during Operation Desert Storm, counter‑insurgency rotations for Operation Iraqi Freedom, and integrated air-ground logistics for Operation Enduring Freedom. II MEF elements supported multinational maritime security operations with Combined Task Force 151 and participated in counter‑piracy patrols alongside Royal Navy and European Union Naval Force task groups. The force also executed domestic support during Hurricane Florence and interagency responses after 9/11.
Training and Readiness
II MEF emphasizes integrated live, virtual, and constructive training across combined-arms domains, participating in large-scale exercises such as Exercise Bold Alligator, Exercise Trident Juncture, Bright Star, and annual unit-level pre-deployment training. Training events incorporate aviation integration with platforms like the F/A-18 Hornet, F-35 Lightning II, and MV-22 Osprey and ground maneuver with systems including the M1 Abrams, Light Armored Vehicle, and M142 HIMARS. Readiness is assessed through certification events, sustainment rotations with U.S. Fleet Forces Command, and interoperability trials with NATO command structures and partner militaries like Japan Ground Self-Defense Force and Republic of Korea Marine Corps.
Command and Leadership
II MEF is commanded by a lieutenant general selected from senior United States Marine Corps leadership. Command relationships span coordination with regional combatant commanders including SOUTHCOM, EUCOM, CENTCOM, and AFRICOM, and with maritime leaders such as the Chief of Naval Operations. Past senior leaders associated with II MEF and its subordinate commands include General Alfred M. Gray Jr., General James L. Jones, and General John R. Allen. The command staff integrates senior officers from aviation, ground, logistics, intelligence, and communications specialties drawn from institutions such as the Marine Corps University and National Defense University.
Insignia and Traditions
II MEF traditions reflect United States Marine Corps heritage, amphibious lore, and unit heraldry displayed at Camp Lejeune and on ship‑borne detachment banners. Insignia and unit emblems draw from historical symbols used by 2nd Marine Division and 2nd Marine Aircraft Wing, and ceremonial observances align with broader Marine Corps events such as Marine Corps Birthday celebrations and Semper Fidelis honors. Unit ceremonies often incorporate commemorations tied to campaigns like Iwo Jima, Okinawa, and Guadalcanal that inform the esprit de corps of II MEF formations.
