Marine Expeditionary Brigade

A Marine Expeditionary Brigade (MEB) is a formation of the United States Marine Corps, a Marine Air-Ground Task Force of approximately 14,500 Marines and Sailors constructed around a reinforced infantry regiment, a composite Marine aircraft group, a combat logistics regiment and a MEB command group. The MEB, commanded by a general officer (usually a Brigadier General), is task-organized to meet the requirements of a specific situation. It can function as part of a joint task force, as the lead echelon of the Marine Expeditionary Force (MEF), or alone. It varies in size and composition, and is larger than a Marine Expeditionary Unit (MEU) but smaller than a MEF. The MEB is capable of conducting missions across the full range of military operations.

In 2013 Maj. Gen. Frank McKenzie stated that as part of the 2013 QDR, the MEB would now become more independent of support from the MEF, as part of a plan to deactivate MEF2.
