Understanding of emotional intelligence and emotional competence for successful individual work not only in the process of their professional development but also in special conditions, including work in military units during military aggression on the territory of Ukraine, was the crucial objective. The importance of emotional intelligence on the psychological compatibility of the unit and the factual existence of such an influence was the topic of our research as it is not examined sufficiently by military experts. We distinguished the category of conscripted personnel and the process of their appointment to new military groups. We also confirm that apart from the process of blending in new communities, the military units were changed in their psychological structure and cooperation, which was also interesting to study. In our work we focused on new paradigm of understanding emotions, based on the theory of emotions construction - we consider it as a radical perspective on what means to be a human, which stands for the newest researches in neurobiology area. Therefore the theory of emotions construction forms the connection of all three directions. It borrowed the idea of cultural influence and perceptions importance from social construction. It also took the postulate, that emotions are constructed by the main brain and body systems from psychological construction and the conclusion that the experience forms the brain links from neuroconstruction. We also highlighted the perspectives on the emotional intelligence of famous psychologists. Reuven Bar-On is an Israeli psychologist and one of the leading innovators, theorists and researchers in the concept of emotional intelligence. The notion of emotional capability was concerned in a book “Emotional Leadership: The Art of Managing People Based on Emotional Intelligence” on the co-authorship of D. Goulman with Richard Boyacis and Annie Mackey. The concept of emotional competence was suggested by David McClelland, a psychologist at Harvard University.Several obstacles that the military experts faced while working with military personnel have been identified. In order to study the level of servicemen’s development of emotional intelligence a Hall test was conducted to diagnose the emotional intelligence. The rapid assessment methodologies presented by S. Mikhalyuk and A. Shalit. were carried out for the study of the socio-psychological climate. The results are not encouraging, but they represent the real state of affairs and the need to address and solve the identified problems.
