ion of the exercise. (iv) Reports. The simulation must provide feedback to the training unit by sending reports of simulated events. These reports must be formatted in a doctrinally correct fashion and occur in a time-appropriate banner. The reports must not reveal all of ground truth but reflect that information that the simulated unit would reasonably know given its status, time removed from the reported incident, and deployed intelligence assets. (v) Human Factors. The simulation must portray the effects of operations on the human condition as it relates to combat effectiveness. At a minimum, the simulation must consider unit morale and cohesion, time subject to hostile actions, availability of religious support, unit attrition rate over time, weather, and operational tempo. (vi) Simulated Mistakes. The simulation must cause simulated entities to "make mistakes" based on a predetermined level of training and a variable combat effectiveness determined by human factors . The mistakes should be of two types: mistakes in actions taken and mistakes in actions reported. Mistakes in actions taken fall along the lines of getting lost e.g., arriving at or attacking the wrong location, delivering the improper quantities of supplies, or delivering the wrong supplies. These types of mistakes will change the ground truth of the simulation. Along with reports that are accurate but incomplete, other reports will contain information that is different from ground truth. These mistakes in reporting will occur when a simulated unit makes a report to the training unit that conflicts with ground truth in the simulation. These mistaken reports will not change ground truth. The simulation must have the ability to provide the correct information if challenged for confirmation. The level of training and combat effectiveness must change over exercise time with a corresponding change in the number of mistakes. ...
