Which Marine Corps entity is known as the senior agency in the command and control system?

The Marine Tactical Air Control Center (TACC) is recognized as the senior agency in the command and control system because it plays a pivotal role in coordinating air operations within the Marine Corps. TACC is responsible for managing air support and ensuring effective integration of aviation assets with ground forces. It serves as the central point for coordinating aviation command and control during both planning and execution of operations.

The functionality of TACC is essential for executing air support missions, directing aircraft in combat, and coordinating with other branches and services. Its senior position in the command and control hierarchy allows it to oversee and harmonize all air requests and ensure they align with operational objectives.

While other entities such as the Marine Air Ground Task Force (MAGTF) and the Expeditionary Force Command Center (EFCC) also play significant roles in military operations, TACC’s specific focus on aviation operations sets it apart as the senior agency for command and control in the context of air support.
