Considering the impact of social determinants on the capacity and well-being of Ukrainian military personnel is critical in military conflicts. This study aims to investigate the influence of social and individual factors on the activity level, determination, and resilience of Ukrainian military personnel during wartime. A qualitative method was chosen to conduct the study. The study involved 130 military personnel who were divided into two groups: those in active combat zones (n = 50) and those in military hospitals for treatment and rehabilitation (n = 80). According to the study, individuals in active combat zones perceive life as a manifestation of the potential received at birth. It was also observed that military personnel receiving treatment and rehabilitation in a hospital understand “life” as a connection with loved ones and close acquaintances. According to the survey results, many respondents from both groups identified their relatives as the military’s primary vital connection during the war. The military’s understanding of “life” and their associations also play a role in determining their need for assistance. In both groups, it can be observed that social determinants, such as relatives and friends, significantly influence the activity of servicemen and women. Individual determinants, such as attitude towards life and the ability to perform under war conditions, are among the factors that impact the military. The study’s practical significance in developing the socio-humanitarian, educational, and cultural spheres is reflected in the formation of awareness of the military and their psycho-emotional conditions in military operations.
