Basic structure of a Marine Air-Ground Task Force Today, the basic framework for deployable Marine units is the Marine Air-Ground Task Force (MAGTF), a flexible structure that can vary in size. A MAGTF is composed of four elements: the command element (CE), the ground combat element (GCE), the aviation combat element (ACE) and the logistics combat element (LCE).[6] A MAGTF can operate independently or as part of a larger coalition.
