The problem of "out of the war" is not less, and perhaps even more complex than the issue of "entry" into it. Even if we consider some psychological consequences, the impact of war on the human psyche is extremely wide. It encompasses a diverse range of psychological phenomena in which the human psyche changes range from distinct, obvious pathological forms to outwardly inconspicuous, hidden, long-acting, as it were "deferred" in reaction time.
Of course, as a percentage of the numerical composition of the armies involved in the hostilities, such cases are not very large. However, throughout the XX century tended to increased military psychogenic disorders in each new armed conflict. Thus, according to American scientists during the Second World War, the number of mental disorders of soldiers has grown up to 300% in comparison with the First World War. According to estimates of international experts, of all the soldiers who participated directly in hostilities, 38% had various mental disorders.
However, international experience in the field of military psychopathology suggests that interest in it abroad for a long time was also small, and grew only in the middle of the XX century. The large-scale manifestation of this problem is in today's wars, where extremely increased technogenic factor imposes unreasonable demands on the human psyche. For example, in the US Army, this problem has been actively studied only during and especially after the end of the Vietnam War, when they were first described by post-traumatic stress disorder (PTSD). In addition, there is the impact of the sciences themselves, exploring the human psyche.
War and participation in it have an absolute effect on the mind, subjecting it to serious qualitative changes. In this circumstance drew attention not only among specialists, but also among writers who percept reality very keenly, vividly, emotionally, including, especially those who had direct military experience. This list includes Leo Tolstoy, Erich Maria Remarque, Ernest Hemingway, Antoine de Saint-Exupéry, and many others.
In such circumstances, the most visible manifestations of the specific impact of war on the psychology of the participants are "front maximalism" syndrome of force and attempts of their application (especially at first) in conflict situations in peacetime.
In the foreground there is a question of adaptation to the new conditions, mental adjustment "for a peaceful way."
