The methodology was descriptive-survey and its statistical population was managers and commanders of the I.R.I Army headquarters, I.R.R Navy headquarters and I.R.R Navy affiliated areas, who are in managerial jobs, subject to an understanding of the concepts of knowledge management, which 66 people were selected through stratified sampling. Data collection tools were library documents, interviews and researcher-made questionnaires, which contained 49 questions and had validity and reliability. Data analysis was performed using descriptive and inferential statistics and one-sample T-test, correlation and multiple variables. The findings of the research showed that at present, managers and commanders do not use the knowledge creation, sharing, and use indicators in their decision making, but they use the knowledge storage component Also, based on the opinion of experts in this study, the component of knowledge sharing has the greatest influence on decision making. And the effect of the knowledge management system on the decision making of military personnel is greater than the staff of other organizations. In the obtained results, there is a significant difference of using Knowledge management in decision making between the views of holders of bachelor and master degree in applying knowledge and knowledge sharing, and between a group of more than 25 years old and employees under 25 years of age, and ultimately between operational staff and other occupations. The overall suggestion is that, given the manager's satisfaction for using the knowledge of knowledge management in decision making, they should be more inclined to review their policies and to formulate supportive and mandatory policies in order to guide the staff in applying the indicators and components of knowledge management such as , Exploiting knowledge sources outside the organization, giving attention to research in the field of decision making, collecting the experiences of the organization's individuals for better decision making, setting up support databases for decision making, etc.
