Evolution of Models at the Warrior Preparation Center
Problems and Solutions for Higher-Echelon Exercises
This report describes the evolution of the suite of models at the Warrior Preparation Center (WPC), a training and support facility in Europe. The study points out that the WPC faced a sudden change in its customer base, which meant that underlying assumptions and exercise designs well suited for that earlier customer base had to be reevaluated. This reevaluation yielded two results: (1) the WPC should strive to reduce in-house model development and model modification and should focus instead on improved training support activities; and (2) the WPC should initiate a new investigation of alternative models and exercise designs without the old institutional assumptions. This result led to the decision that the WPC should have two sets of models--one for Army Group and above and another for Army Group and below. The project staff recommended the Corps Battle Simulation (CBS) model to replace WPC's ground war simulation (GRWSIM) model for lower echelon exercises and the joint theater-level simulation (JTLS) model for higher-echelon training.
