Which element is NOT part of the MAGTF structure?

The Joint Forces Command is not a component of the Marine Air-Ground Task Force (MAGTF) structure. The MAGTF is specifically organized into four main elements to effectively execute its missions: the Ground Combat Element, the Aviation Combat Element, the Logistics Combat Element, and the Command Element.

The Ground Combat Element is responsible for ground operations, the Aviation Combat Element provides air support, logistics support encompasses all the sustainment necessary for the MAGTF to function, and the Command Element integrates and leads the operations. Joint Forces Command, however, pertains to broader joint operations that involve multiple branches of the military working together, and is not a structural component of the MAGTF itself. Thus, this distinction makes it clear why it is not included as a part of the MAGTF.
