One of the important and relevant problems of social psychology is the study of the role of will characteristics as important regulators of risk behavior. It is especially interesting to investigate it in such a specific social group as military personnel, whose activities are associated with risk both directly and indirectly. In view of this, the purpose of the research presented in the article is to study changes in volitional determination of risk and rational behavior of the military university students in the process of professional military socialization.
