Intermediate-sized Marine Air-Ground Task Force in the United States Marine Corps
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 infantryregiment, a composite Marine aircraft group, a combat logistics regiment and a MEB command group.[1] 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.
