The use of simulation applied to combat situations has a long history, going back to the beginning of the 20th century, and it is usually applied to areas of analysis and training outside of wargaming. Wargaming, on the other hand, has its modern roots going back to the first half of the 19th century, and has proven to be extremely effective at giving military planners and analysts insights into possible future conflicts, as well as an invaluable method at evaluating current and past operations. By combining these two areas, the data driven speed and details of computer simulation can be combined with insight and analysis provided by wargaming, however the two communities do not seem to be aware of each other. Where there is current involvement, there is misunderstanding on both sides of what the other has to offer. The editors, and authors of the chapters, as proponents of both, see a way in which this can be presented to both communities at large, to bridge the gap, and allow practitioners and researchers a way ahead to involve both techniques together. By combining the two areas of wargaming and simulation, this book shows how the practice of wargaming can be augmented and provide more detail-oriented insights using computer simulation. The use of such simulations in wargaming does not come without concerns (and may not be universally desirable), and those are the areas that are addressed within this book.
