The Department of Defense has been implementing a number of commercial PC simulation games to support surface, subsurface, and battle group individual and team tactical training. Many of these low cost games offer realistic and accurate graphical and dynamic depictions of U.S. and foreign surface ship, air, and submarine platforms. In addition, the sophisticated 3-D visualization, challenging tactical scenarios, and the high level of interactivity presented in the current generation of PC games is appealing to today's computer-literate young officers and enlisted personnel, creating a potentially effective learning environment. Conversely, features added to some products to increase entertainment and gamesmanship for the broader commercial audience may misrepresent actual combat situations, conditions, or available information that could adversely impact potential training value. This paper examines the advantages and disadvantages of using commercial PC games for naval training applications and offers recommendations and guidelines for integration of these products into Navy training curricula.
