USAREUR has increased its training effectiveness by maximizing the use of the latest training technologies. Its unique training strategy to maintain readiness for diverse and changing missions is described. A combination of live, virtual and constructive training resources are used at all echelons for individual, collective and leader training. The application of training resources individually or combined and integrated by means of Distributed Interactive Simulation (DIS) to create realistic/seamless brigade, corps and multinational training is outlined. The techniques used to assess training and leverage its value through feedback are discussed. By these means, training resources have been cascaded resulting in synergisms that provide higher levels of training effectiveness at substantial cost savings.
