Philip Sabin (a military historian at King's College London) recently published an excellent book on the use of wargames for education, research, and policy development: Simulating War: Studying Conflict Through Simulation Games (London: Continuum, 2012).
While the book is heavy on his own experiences at KCL using boardgames, it is nevertheless an excellent read (and certainly the best academic wargaming book since Peter Perla's The Art of Wargaming). You'll find my own review of it at PAXsims.
