The Marine Expeditionary Brigade (MEB) is a mid-sized Marine Air-Ground Task Force (MAGTF) that is typically comprised of about 14,500 Marines and Sailors. It is designed to be a self-sustained, rapid response force that can operate independently or as part of a larger military operation.
In terms of relative size, the MEB is smaller than a Marine Expeditionary Force (MEF) but larger than a Marine Expeditionary Unit (MEU). It provides a balance of ground, air, and logistics forces to conduct a wide range of military operations, from humanitarian assistance to full-scale combat.
Typical employment of the MEB includes crisis response, expeditionary operations, amphibious assaults, and providing security and stability in various regions around the world. They are often deployed in response to emergencies or conflicts where a larger force like a MEF is not required, but more capabilities than a MEU are needed.
