Engagement Simulation (ES) has filled a training need for maneuver forces by realistically assessing casualties and by replacing fixed scenario exercises with free play interchanges where opponents' actual behavior determined exercise results. Artillery was not integrated into ES, however, and the goal of this research was to develop a realistic and inexpensive ES method for training artillery units. A computational system, which used the data actually set on the guns and employed standard fire direction equipment, was designed to select the probable impact point of artillery rounds. This meant that the behavior of artillerymen directly affected the placement of artillery simulators on the ground. Thirty-six simulated missions were "fired" by an artillery battery during a developmental test. Targets on the ground were assigned to a forward observer and simulators were placed based on the computed impact points. Feedback on mission effects was provided. Results indicated that the artillery system improved its speed and accuracy.
