I thought people here would be interested in an article that I stumbled across recently. It is titled Choreographing the Dance of the Vampires: Red Storm Rising’s Game Plots by Matthew Kirschenbaum and was originally published February 24, 2012. It is about how the Harpoon war game was used by Tom Clancy and Larry Bond to help plot out the events of the Red Storm Rising chapter “The Dance of the Vampires.”
