a group of 305 male subjects aged 20-43 y.o. participated in military operations and exhibited ICD-10 specified symptoms was studied. Of this group 174 subjects committed different personal crimes after their return into the peaceful socium.

In subjects, manifested violent behaviour, PTSD was dominated by symptoms of intrusion (the repeated experience of stress situation) in the form of obsessive ideas, fantasies and reminescences; in dreams and nightmares; in situations associated with stress experience as well as the symptoms of hyperexitation (irritability, inclimation to conflicts, unstable mood). More over, combinations of these symptoms with feeling of “psychologically toxic guilt; including the guilt for the cruilty at war, the fault for those who had to stay at war, and the guilt for those who fell in battle. In combatants without violent manifestation in time of peace PTSD was determined by the symptoms of the “escape” against the background of vegetative and psychosomatic disorders associated with rudimentary unstable symptoms of intrusion and hyperexitation.

The revealed qualitative personal disorders may be considered as predisposing factors or the reasons of the combatant's socially dangerous behaviour.
