It is necessary to fight for military power. In addition to weapons, technology, the existence of various by-laws, especially operational and martial law, is essential in the strategy of exercising military power. The bylaws teach the techniques and methods of fighting to the military. The overall purpose of this study is to explain the application of the Code of Conduct in the exercise of military power by the Islamic Republic of Iran. The type of research applied is correlational. This article is written in an analytical-descriptive approach and attempts to elaborate on the application of operational and combat codes in the exercise of military power by the Armed Forces. The statistical population of the study includes the commanders and successors of the regional headquarters and the deputies of the AJAF and IRGC. Data collection was done through two questionnaires on the application of martial and operational codes of conduct and the strategy of applying military force to the armed forces. Kolmogorov-Smirnov test and Pearson correlation coefficient were used to investigate the relationship between the independent variable and the function variable. At the significant level of five percent (5%) the validity of the research hypotheses was confirmed. The results showed that the component of military operations design had the most influence on the military power use of the armed forces. And among these is the preparation of staff estimates, commanders' decision-making, and the preparation of an operational command to enter the field of operations and the combat zone.
