Abstract: On the basis of game theory, and taking the air formation to ground attack-defence cam?paign as the background, we established an opposed dynamic decision-making model. Aiming at the proolems in military decision-making under stochastic condition in uncertainty, we put forward a factor of stochastic influence, which reflects the influence of stochastic condition on battling units, and estab?lishes stochastic opposed decision-making models in anticipant value and in correlative chance way far?ther .It can be seen from the simulating results that the models can dispose the stochastic status in bat?tlefield reasonably, analyse the fighting result impersonally, and offer a powerful decision-making sus?taining for military command and control. The proposed method is very practical and effective, and has a good apolving future.
