The purpose of the article is to analyze the existing training of military serviceable personnel in the Ukrainian citizens, to develop directions and prospects for developing the system of the Armed Forces of the Ukrainian Armed Forces, to determine the highest mobilization potential among the areas of operational command "PIVNICH" and operational command "West" and most prospective group. Method. The research was conducted on the basis of analysis of available literature sources on this topic and practical component of 2014 mobilization. The available statistical materials of the region were worked out, and the materials collected on the basis of which were drawn up maps of mobilization potential and qualitative structure of human resources. Results. Theoretical, methodological and practical problems of mobilization potential in the troops are investigated. The tendencies and prospects of development of these processes in the military sphere are analyzed. The leading tasks, the solution of which promotes the mobilization potential are substantiated. In the article, on the basis of the analysis of the existing system of training, mobilization in 2014 and passage of military service by the citizens of Ukraine, the mobilization potential of the regions of the country is determined. On the basis of the analysis of the age structure of the personnel called for mobilization, the most promising age group for the protection of the state was determined. A new approach to the mobilization potential of the state is determined and its components are elaborated. Scientific novelty. The necessity of this research is caused by the fact that since 2014 and till now there are fighting in the east of our country, it is not clear which regions have the greatest mobilization potential, considering not only human resources, but also the desire to fight for their state and if necessary give your life. To date, there are no identified factors that increase the mobilization potential in the regions that contribute to its improvement and, accordingly, the factors that aggravate this situation, which is what led to this study. Practical meaning. Modeling and analysis identify which areas have the highest mobilization potential, as well as the least, identify the factors that cause it and what measures should be taken to remedy the situation. The results of the study are designed to plan state structures for possible mobilization resources, from each area as needed, including a larger scale of hostilities. The geographical features that should be given the most attention in the analysis of the military potential of the military potential are highlighted.
