Trainers for collective exercises control the exercise by manipulating mission, enemy, terrain, troop, and time (METT-T) situation variables to support a training or exercise objective. The feedback system must then examine the performance of a unit as a function of the evolving METT-T situation. Integration of exercise control and feedback functions is necessary to reduce and simplify the workload of trainers and to make sure exercise control and feedback systems are mutually supportive. Integration is especially crucial in the Distributed Interactive Simulation (DIS) environment for two reasons. First, efficient use of training resources requires substantial temporal overlap and competition between exercise control and feedback functions to provide rapid feedback. Second, the exercise control function expands to include controlling the behavior of enemy and friendly computer generated forces (CGF). This paper describes current problems integrating state of the art exercise control and feedback systems in the DIS environment and presents potential solutions requiring research and development.
