II Marine Expeditionary Force (MEF) is one of three MEFs in the Marine Corps. I MEF is in California and III MEF is in Okinawa.
A MEF is a combined arms force consisting of ground, air and logistics forces. It possesses the capability for projecting offensive combat power ashore while sustaining itself in combat without external assistance for a period of 60 days.
With more than 47,000 Marines and Sailors, II MEF is representative of the largest and most powerful Marine Air-Ground Task Force (MAGTF). The MAGTF concept is flexible and scalable under single commander. MAGTFs provide Joint Force Commanders the following capabilities:
-Humanitarian support and natural disaster relief operations
-Rapid crisis response
-Ability to operate independent of established airfields, basing agreements, and over-flight rights
-Ability to train with allied forces as part of a theater engagement plan
-Forward deployed, credible deterrent force
II MEF is comprised of four basic components:
(1) II MEF Information Group containing personnel and equipment necessary for the effective planning and execution of operations.
(2) A ground combat element, the 2d Marine Division.
(3) An aviation combat element, the 2nd Marine Aircraft Wing.
(4) A combat service support element, the 2nd Marine Logistics Group.
