Military simulation: A ubiquitous future

The Department of Defense uses Modeling and Simulation (M&S) to support a variety of activities ranging from engineering to theater-level analytical studies, training, strategy evaluation and test. To conduct these activities, different simulation types have been identified and defined as shown in Figure 1. For each type: Live, Virtual, and Constructive (LVC), the essential difference is based on how aspects of reality are included, specifically from people or a system of interest. While this categorization is useful, the level or degree of realism is not specified.
