In this image released by the 75th Training Command, a scene from Ellington Field Joint Reserve Base is shown during a simulation training exercise in Houston, Texas, Saturday, Oct. 20, 2012. The exercise was part of an effort to demonstrate a system developed by the 75th to allow various military units to conduct certain types of scenario-based war game training over computer networks. Using the system, reserve component military units are able to train in leadership and mission management tasks with a high degree of realism, and a low overall cost.
