Which system is primarily used for coordinating artillery and mortar fire?

The Fire Direction Center (FDC) is the primary system used for coordinating artillery and mortar fire. Its main function is to receive target information from forward observers, process the data to determine firing solutions, and communicate those solutions to the firing units. This ensures that artillery and mortar units can accurately deliver fire on target, adjusting as necessary based on the changing tactical situation.

The FDC plays a critical role in the fire support process by integrating data from various sources, including forward observers and reconnaissance units. It applies techniques such as range computation, trajectory analysis, and time management to ensure effective fire support. The FDC effectively orchestrates the multiple steps required to ensure that fire missions are executed accurately and efficiently.

In contrast, other systems such as the Joint Tactical Air Control System, Field Artillery Targeting System, and Combat Operations Center serve different roles within military operations. While they may have some overlap in terms of coordination and communication, they do not focus specifically on the detailed technical process of determining and directing artillery and mortar fire as the FDC does.
