The main idea of any military force is known in the form of its doctrine; doctrine is a mental thing and a set of beliefs and knowledge that has been proven by experience. Military doctrine is a framework for the use of forces, equipment, and tactics in war. Victory in the future wars will be possible when Nezaja adjusts its operational structure to the levels of war and military doctrine. According to the available documents, war and doctrine have three levels: tactical, operational and strategic. In the current structure of AJA and Nezaja, there is no technical and meta-strategic level. This study aims to explain the operational structure of Nezaja based on the levels of military doctrine and future wars. This developmental-applied study has been done by field-case based method. The statistical population is 50 military elites with the rank of brigadier general and above who have at least a bachelor's degree and have been the commander of the division and brigade for three years. The method of data collection is field and library. Findings are analyzed using expert methods. The results of the research indicate that the future war has 5 levels of doctrine and 5 levels of implementation: technical, tactical, operational, strategic and supra-strategic levels. In order to reduce the levels and layers of command, the operational structure of Nezaja in the future war is in the form of companies, battalions, divisions and Nezaja. In this structure, two layers of brigade command and regional headquarters are eliminated. At present, the structure of Nezaja is brigade-oriented and headquarter-based, so its approach is threat-oriented and action-oriented. If the structure of Nezaja is based on battalions and divisions, its approach will become security-oriented and supra-actional. This article does not seek to change the organizational structure of Nezaja, but to look at the organization for combat and the operational structure of Nezaja in a possible future war.
