I didn't check the link yet (watching "so you think you can dance") but we got to sit through a briefing with Lcol Grossman of the US. It discussed the same topic. It's interesting to see how we can "innoculate" ourselves a little bit by preparing for the stress and the reaction to killing. And to realize that when we get back, we will most likely be a little affected by the incidents we have experienced but as with a small wound, all that is needed is a little medical attention and we shouldn't be ashamed to ask for it.
