The article examines the impact of training sessions on the combat army system (BARS) on the formation of physical readiness of future officers for professional combat activities in the process of training in a military institute of higher education. Cadets of 2-3 courses (n=62) of S.P. Koroliov Zhytomyr Military Institute took part in the research. Two groups were formed: experimental (EG, n=32), whose cadets studied in the section of the institute on the combat army system, and control (CG, n=30), whose cadets studied under the current system of physical training in military institute. It was found that the level of development of physical qualities and the formation of military-applied skills in cadets who studied in the section BARS, at the end of the study is significantly higher than those who were engaged in physical training during sports and mass work. The most pronounced effect of BARS classes was found on the development of strength qualities, strength (static) endurance, as well as on the formation of professional military-applied skills in overcoming obstacles.
