Introduction. With today's changes, Ukrainians are directly involved in a local military conflict. That is why our society needs to create an army of a new model. An army that is optimal in numbers, soldiers who will be professionals in their own business, will own new weapons and will be able to think critically in extreme situations. One of the key features of conscript service is the adaptation of future servicemen to the conditions of the military unit, to their chosen specialization, to the individual and psychological qualities of their companions and officers. That is why the successful adaptation of the recruiter to the conditions of the military unit will ensure the proper acquisition of knowledge and skills that require specialization, which will subsequently become the basis for becoming a soldier as a professional.The purpose of the article is to elucidate the results of the study of the features of adaptation of conscripts in terms of military unit. Achieving this goal was carried out in several stages, where it was first necessary to identify the psychological factors of adaptation of servicemen, which will contribute to the flow of its effectiveness; the purpose of the second task was to carry out an experimental study of the study of this problem; The third stage is aimed at developing practical recommendations for improving the adaptation of military personnel.Methods The following set of psychodiagnostic techniques were used to solve the tasks: to identify the level of adaptive capacity of the individual, the “Multiple personal questionnaire“ Adaptability - 200 ”technique was used; to identify the level of influence of psychological states was used the method of "Self-assessment of mental states of G. Eysenck"; to identify the level of influence of accentuating personality traits was used the method of "Characteristic questionnaire of K. Leonhard and X. Shmishek; to determine the level of influence of personality temperament was used the method of "Personal Questionnaire (ERI) G. Eysenck".The originality of the work is that they can be used to promote the level of adaptation of military personnel. The diploma materials are recommended to be used in the course of training sessions on the adaptation of conscripts, as well as to the psychologists of the military units in order to improve the process of adaptation and correction of psychological states that directly affect the adaptation.Conclusions. Thus, the key factors in the adaptation of military personnel are psychological states, temperamental and character traits of the individual. It has been found that the presence of a certain level of manifestation of the above-mentioned features causes an appropriate level of personality adaptation. That is, the lower the level of accentuation of character, psychological states and extraversion of personality, the higher the level of adaptation of servicemen and vice versa.The experimental research we conducted does not exhaust all aspects of our study. We see the prospects for further searches in studying the motivational aspect of military personnel as a factor of adaptation.
