Which Marine task force comprises integrated, combined arms forces including air, ground, and logistics under a single command?

The Marine Air-Ground Task Force (MAGTF) is the correct choice because it represents a versatile and unified force structure that integrates all the essential components of a Marine Corps operation, including aviation, ground combat, and logistical support, under a single command. This integration allows MAGTFs to effectively conduct a variety of missions and operations, leveraging the strengths of each element to achieve common objectives.

The MAGTF is designed to be scalable, facilitating operations ranging from routine peacetime missions to full-scale combat operations. This capability is essential for the Marine Corps, as it emphasizes their core strategy of being expeditionary and flexible, able to respond quickly to emerging situations across different environments.

In contrast, while the Special Purpose MAGTF (SPMAGTF) and Marine Expeditionary Brigade (MEB) are specific types of task forces with certain operational focuses, they do not encapsulate the same broad integrated approach as the MAGTF. The Marine Expeditionary Unit (MEU), while composed of combined air-ground forces, operates at a smaller scale compared to the full capabilities offered by a MAGTF, which can adapt to larger contingencies and provide a more comprehensive force structure.
