What organization assists the Marine air-ground task force commander with fire support planning and coordination?

The Fires and Effects Coordination Center (FECC) is specifically designed to assist the Marine air-ground task force commander with fire support planning and coordination. It plays a pivotal role in integrating and synchronizing all fire support assets, ensuring that artillery, naval gunfire, and close air support are effectively coordinated to achieve the commander’s intent. The FECC works to prioritize targets and manage the flow of information and requests related to fire support throughout operations, allowing for more efficient and effective use of available firepower.

While the other options also involve aspects of fire support within the Marine Corps structure, they serve different functions. The Fire Support Element (FSE) is focused on immediate coordination of fire support in the field but does not manage broader coordination like the FECC. The Fires Element (FE) and the Fires Cell (FC) may also deal with fire support coordination, yet their roles are typically more focused on specific tasks within a unit rather than the overall integration that the FECC provides across the operating environment. Thus, the unique role of the FECC in synthesizing fire support operations makes it the correct answer.
