The paper presents the solution to an impor-tant academic issue related to the analysis of methods of overcoming psychoemotional stress in war. There are three main types of stress that occur during war: combat, traumatic, and posttraumatic. The differences of the described varieties are determined and their nature is established, the latter consists in the action of stressors of exceptional strength, which determines the combination of physiological and psychoemotional symptoms. In this regard, biological (related to the physiological nature of stress) and psychological theories are analyzed.According to biological theories, stress is a violation of the body’s balance between external influences and internal resources of the body, which fact out-lines the main methods of overcoming it. According to these theories, methods aimed at attracting physiological resources of the body (rest, sleep, relaxation); restoration of disturbed psychophysiological functions (normalization of respira-tion, acquisition of control over the body); provision of basic needs (food, water, heat, hygiene). According to psychological theories, stress is characterized as an internal mental state of tension that determines the methods of overcoming it. For the treatment of combat stress, the BICEPS program (brevity, immediacy, centrality / contact, expectancy, proximity, simplicity) is presented, which is widespread in US military practice. To overcome the traumatic and posttraumatic stress of civilians, a number of methods of psychological and psychotherapeutic care have been proposed, including psychocounseling, debriefing, crisis intervention, defusing, autogenic training techniques, rational, cognitivebehavioral, physical therapy, therapy and neurotherapy.conclusions. Summarizing the theoretical and methodological positions of the study, two main areas of influence on the symptoms of psychoemotional stress are identified:1) impact on physiological aspects of life, including the satisfaction of basic human needs for food, warmth, hygiene; increase of physiological resources of an organism and restoration of the broken psychophysiological functions; 2) in-fluence on psychological factors of behavior (motivation, value system, volitional characteristics) by means of psychological counseling, psychological rehabilita-tion and psychotherapy.Their use is effective in a complex, which will increase the impact on both psychological and physiological factors of stress formation.Key words: stress, combat stress, traumatic stress, posttraumatic stress disorder, war.
