The technique of pedagogical modeling is reasonably considered in education as a promising direction of the development of theoretical and practical knowledge. Modeling involves not only the creation of a theoretically based model of future professional development, but also a practical justification, confirmation of the functioning of the created model. Modeling professional mobility of a future officer of a military university is of practical interest not only in the pedagogical field, but is also determined by the tasks of national development and national security of the Russian state in the short term. An unambiguous determination of the algorithm for the formation of all components of the professional mobility of a military specialist includes the development of personal and social professional mobility. The structure of the model, proposed in this article, was formed as a result of the generalization of modern theoretical knowledge, as well as experimental research, based on the leading military universities of Russia.
