What is The largest Marine Air-Ground Task Force?

The largest Marine Air-Ground Task Force (MAGTF) is the Marine Expeditionary Force (MEF). It is a combined arms task organization that includes ground, air, and logistics units, capable of conducting a wide range of military operations. A MEF typically consists of a Marine Division, an Aircraft Wing, and a Logistics Group, along with supporting elements, and is designed to be a self-sustained, rapid-response force.
