ABSTRACT
The article presents the investigational results of psychophysiological and social-and-psychological adaptation to military service in conditions of the European North of Russia in servicemen called up from different regions. During the first 6 months the positive dynamics concerning the communicative and personal adaptation potential and behavioral regulation was noted in all 239 servicemen. It was established that the representatives from northern region have lower potential possibilities of social-and-psychological adaptation to military service in the European North of Russia than the youths called up from other regions. Social-and-psychological adaptation to military service in the northern conditions was better than in the persons called up from the southern and central regions. The complete adaptation of servicemen at biological level wasn't observed.
