The central contribution of game theory to defense analysis has been a language for the understanding of how to formulate and study strategic or cross-purposes optimization in situations involving two or more actors. It is suggested here in this discussion that two fundamentally diﬀerent classes of application of game theory to problems in defense have emerged. The ﬁrst is the application of two-person zero sum game theory to military, primarily tactical situations which for the purposes at hand can be reasonably well modeled in this manner. The second is the application of two or more person nonconstant sum game theory to strategic problems involving threat analysis, crises control and the interface between international diplomatic relations and war.
