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.
