Name one type of fire direction center (FDC) support system used with the M119A3.

The Advanced Field Artillery Tactical Data System (AFATDS) is a crucial fire direction center (FDC) support system used with the M119A3. It serves as an automated system that helps in the coordination and execution of fire missions. The AFATDS integrates various data inputs, including target location and artillery positioning, to facilitate accurate and timely delivery of fire support.

By utilizing sophisticated algorithms, the AFATDS enhances decision-making by providing commanders with real-time information. This system enables the artillery crew to efficiently calculate firing solutions, assess enemy targets, and manage fire missions based on the battlefield situation. Its integration with the M119A3 ensures that the artillery unit can effectively support maneuver forces and respond quickly to changing combat conditions.
