Abstract: The collaborative activities of the military decision making are variable and complex.When coalition members must work together，these differences may be very large，puzzling and abortive.Coordination theory provides a method for modeling complex collaborative activities in a way that makes both the similarities and differences between them more distinct.To depict this，we model parts of the decision-making process as defined in a field manual 101-5.The methods for coordination defined in this model are all about the collaboration processes.This approach will help to integrate different processes to improve the adaptation of military decision making.
