The doctoral dissertation deals with the historical overview and military-geographical analysis of operational activities in the Šibenik hinterland area, with special reference to the tactical operation "Miljevci" conducted in June 1992. The analysis of operational activities is based on a methodological framework of the operational preparation of the battlefield. Operational preparation of the battlefield is a set of environmental analyzes of a certain geographical area interdependent with the decision-making process. By using modern methods and techniques of operational analytics within the framework of Hi Tec (high technology) and STEM (science, technology, engineering and mathematics) fields, it is possible to compare research results with already conducted activities. With such an approach, it is possible to give a new dimension to the tasks carried out, to confirm or deny decisions that at the time of adoption had a significantly different methodology. The objectives of the research are the reconstruction of the battlefield, the comparison of the conducted operational activities with the results of modern analyzes, and optimization of the movement of personnel and operational techniques in the operational area, with special reference to the karst relief.
