Introduction and objective: The experience of the war in Ukraine shows that success in the field of medical protection of the population can only be ensured by a complete service, tailored to the nature of operational activities, using solutions that allow the use of the latest organizational and technological achievements in the area of health and care. The aim of the study was to develop a new method for dynamic planning of medical support for combat troops by modeling battlefield medical care processes, aimed at increasing the effectiveness and efficiency of health care system resource management and improving the operational capabilities of combat troops. Material and methods: The modeling of battlefield medical care processes was based on commonly recognised operational factors – force, time, area, expanding this group with an additional parameter, important from the point of view of organising the work of medical field units – safety. Results: A proposal for a calculation model was developed on the basis of which an analytical tool was compiled that allows for flexible adjustment and combination of the goals and needs of medical care – regulated mainly by the scale and structure of sanitary losses, with progress in the course of the military operation. Conclusions: The proposed model for estimating medical needs in the part related to securing military operations is a methodologically advanced and at the same time easy to use decision support tool in the planning and organisation of care. It integrates knowledge about the occurrence and distribution of the most important factors determining the conditions and possibilities of providing medical assistance as well as the needs and expectations resulting from tactical and operational intentions. Optimises battlefield medical security processes. Reduces the risk of errors in the most sensitive areas that are crucial to the success of a military operation. Strengthens the health care system’s resistance to hybrid and military operations by providing key information regarding the current needs for its organisation and functioning in connection with tactical and operational plans and the state defence strategy. The concentration and coordination of medical resources carried out using it, both native – assigned to the combat group, and those located in the operational space, creates an environment ensuring high effectiveness and efficiency of the assistance provided.
