His treatment for war neurosis was simple: the patients were to be bullied and harassed until they returned to front line service.Earlier, during the Winter War, several Finnish machine gun operators on the Karelian Isthmus theatre became mentally unstable after repelling several unsuccessful Soviet human wave assaults on fortified Finnish positions. Post-World War II developments
Simplicity was added to the PIE principles by the Israelis: in their view, treatment should be brief, supportive, and could be provided by those without sophisticated training. Peacekeeping stresses
Peacekeeping provides its own stresses because its emphasis on rules of engagement contains the roles for which soldiers are trained. Causes include witnessing or experiencing the following:

Constant tension and threat of conflict. Threat of land mines and booby traps. Close contact with severely injured and dead people. Deliberate maltreatment and atrocities, possibly involving civilians. Cultural issues. Separation and home issues. Risk of disease including HIV. Threat of exposure to toxic agents. Mission problems. Return to service. Pathophysiology
SNS activation
Many of the symptoms initially experienced by people with CSR are effects of an extended activation of the human bodys fight-or-flight response. The fight-or-flight response involves a general sympathetic nervous system discharge in reaction to a perceived stressor and prepares the body to fight or run from the threat causing the stress. Catecholamine hormones, such as adrenaline or noradrenaline, facilitate immediate physical reactions associated with a preparation for violent muscular action. Although the flight-or-fight-response normally ends with the removal of the threat, the constant mortal danger in combat zones likewise constantly and acutely stresses soldiers.
A military leader is extremely effective in this area of treatment. Of all the things said to a service member experiencing combat stress, the words of his small-unit leader have the greatest impact due to the positive bonding process that occurs during combat. Simple statements from the small-unit leader to the service member that he is reacting normally to combat stress and is expected back soon have positive impact. Small-unit leaders should tell service members that their comrades need and expect them to return. When they do return, the unit treats them as every other service member and expects them to perform well. Service members suffering and recovering from combat stress disorder are no more likely to become overloaded again than are those who have not yet been overloaded. In fact, they are less likely to become overloaded than inexperienced replacements. Proximity
In mobile war requiring rapid and frequent movement, treatment of many combat stress cases takes place at various battalion or regimental headquarters or logistical
units, on light duty, rather than in medical units, whenever possible. This is a key factor and another area where the small-unit leader helps in the treatment. CSC and follow-up care for combat stress casualties are held as close as possible to and maintain close association with the members unit, and are an integral part of the entire healing process. A visit from a member of the individuals unit during restoration is effective in keeping a bond with the organization.
