Among all of the reasons that other Freepers have pointed out to show that this study is meaningless, there is the added aspect of the suicide rate of war veterans vs. peacetime military personnel, because, guess what, military personnel who never go to war also kill themselves on occasion, as do civilians. So, even if we were to accept that there was a particular rate of suicide among veterans, it would not necessarily have a bearing on the wars, or conduct of wars. For example, the military has always had a relatively high rate of suicide attempts during holidays even in peacetime - young kids in a somewhat stressful job away from home, often for the first time.
I first encountered this phenomena in 1981. It was on a mimeographed piece of paper taped to the back of a lounge chair in my dorm’s break room. Only then the subject was Vietnam vets and the cause was Selective Service enrollment.
There are 100's of stories about this 'study;' starting back in 2008 when ... 18 veterans/day were commiting suicide. See the link below:

Back in 2008 a story reports that the VA Hid Suicide Risk and there are about 18 suicides per day

18 veterans commit suicide/day in 2008 and still ... 18 veterans commit suicide/day in 2010 - something strange about the number of suicides/day never changing.
