Urban Terrain Module (UTM) using the Dynamic Interactive Virtual Environment (DIVE): The employment of fires and effects in an urban environment is by far the most challenging for the JFO. The requirement to limit collateral damage and non-combatant casualties places tremendous demands on the observer and requires the highest level of technical and tactical skills. The UTM provides a small-scale virtual environment for dismounted personnel to call for and adjust fires and effects that enables potential joint training using a virtual reality simulator. The UTM includes interchangeable walls, high definition rear projection and photo-realistic urban cityscapes populated with simulated controller-initiated computer graphic events. The UTM allows the use of a wide range of military optical/range finding equipment, which, when combined with “live” sets, props, directional sound, and 4D effects, like wind, dust, lighting, explosions and room temperature variations from 55°F to 110°F serve to fully immerse the soldier in the rigors of combat like situations.
