  A novel approach is provided for evaluating the benefits and burdens from
vehicle modularity in fleets/units through the analysis of a game theoretical
model of the competition between autonomous vehicle fleets in an
attacker-defender game. We present an approach to obtain the heuristic
operational strategies through fitting a decision tree on high-fidelity
simulation results of an intelligent agent-based model. A multi-stage game
theoretical model is also created for decision making considering military
resources and impacts of past decisions. Nash equilibria of the operational
strategy are revealed, and their characteristics are explored. The benefits of
fleet modularity are also analyzed by comparing the results of the decision
making process under diverse operational situations.
