The United States (US) Army Research, Development and Engineering Command Simulation and Training Technology Center (STTC), as a cooperative research effort with the United Kingdom's (UK) Land Warfare Center, will be conducting experimental training exercises to evaluate Massively Multiplayer On-line Game (MMOG) technology. The goal is to run three exercises over the next 24 months, starting with a ground exercise and working toward a Close Air Support exercise. The first exercise, which will be conducted in July 2008, will contain several scenarios focused on Assaults, Hostage Negotiations, and Non-combatant Evacuation Orders. The purpose of these exercises is to conduct cooperative research activities that will enhance the technologies, processes, and strategies for applying distributed simulation to Coalition training. The exercises will be conducted in a distributed fashion, where both the US and UK Soldiers will be participating in the training experiment from their respective locations. Exercise control, role players, and after action review will also be distributed over the World Wide Web. Several technical research topics will be explored including: bandwidth constraints, network latency, network security, and scalability. In addition, the United States Army Research Institute will conduct formative evaluations, evaluating task performance, training strategy, and leadership feedback.
