Well, it's difficult to prepare soldiers for these kinds of horrific situations. There is no doubt that if a soldier who has children witnesses events involving children, whether they are victims or whether they're carrying weapons, while on a mission, his conception of life could be turned upside down by what he has witnessed. How can this problem be managed when they come home? Well, it depends on how much trouble he has coping. Whether or not he is suffering from post-traumatic stress, he can receive psychological support that will help him come to terms with those events and find meaning in them. The important thing is to avoid that having a negative impact on the ability of the family to function normally.
In fact, I believe that illustrates why it is important not only to act on soldiers' individual symptoms, but also consider the broader impact—in others words, the systemic effect or effect on the family.
