Which entity is the senior agency within the Marine Corps Command and Control System?

The Marine Tactical Air Control Center (TACC) serves as the senior agency within the Marine Corps Command and Control System due to its critical role in coordinating and integrating aviation fire support operations. As a command and control node, the TACC oversees various aspects of air operations, including the management of airspace, directing aircraft, and facilitating communication among different units. This centralization of authority allows for efficient decision-making and execution of air operations, ensuring that air support is effectively integrated within ground operations.

The TACC is specifically tasked with managing Marine Corps aviation assets and liaising with other military branches when necessary, which underscores its senior position within the command structure. Additionally, the TACC operates in sync with other entities such as the TAOC and TACC of the Navy, but ultimately, it maintains the broader strategic oversight required for successful mission execution within the Marine Corps framework. This position within the command and control system highlights the TACC's importance in ensuring coordinated air support in various combat scenarios.
