The paper dwells upon modern technologies used to develop mental hardiness in cadets of the military higher school. The research suggests that case study, computer games, virtual and augmented reality glasses and helmets, learning topography and digital maps of the possible battlefields should be effective pedagogical technologies for developing hardiness as the attitudes of commitment, control and challenge. To prevent stressrelated problems, it is important to use technologies in the context of cognitive and integrated approaches through creating awareness and understanding of different scenarios of future events for developing mental hardiness of the cadets during their professional training. We also tried to investigate the level of hardiness of adjuncts and post-graduates in comparison with cadets of the military higher school. We used S. Maddi's Personal View Survey, adopted by D.A. Leontiev and E.I. Rasskazova, and measured commitment, control and challenge in the adjuncts and post-graduate students who had an online survey and the cadets who had their paper forms. 53 respondents took part in the survey. The results of the survey analysis showed that the adjuncts and post-graduate students who had a practical experience of military service in airborne troops were significantly higher in hardiness than compared to non-graduates of the higher military school. In the research, we offer to use a complex of modern technologies for developing mental hardiness in the cadets of the military school.
