From the suicide note of Iraq war veteran Daniel Somers, who killed himself the other day. He was 30, married, and suffered from a variety of war-related mental and physical conditions:

My body has become nothing but a cage, a source of pain and constant problems. The illness I have has caused me pain that not even the strongest medicines could dull, and there is no cure. All day, every day a screaming agony in every nerve ending in my body. It is nothing short of torture. My mind is a wasteland, filled with visions of incredible horror, unceasing depression, and crippling anxiety, even with all of the medications the doctors dare give. Simple things that everyone else takes for granted are nearly impossible for me. I can not laugh or cry. I can barely leave the house. I derive no pleasure from any activity. Everything simply comes down to passing time until I can sleep again. Now, to sleep forever seems to be the most merciful thing.

You must not blame yourself. The simple truth is this: During my first deployment, I was made to participate in things, the enormity of which is hard to describe. War crimes, crimes against humanity. Though I did not participate willingly, and made what I thought was my best effort to stop these events, there are some things that a person simply can not come back from. I take some pride in that, actually, as to move on in life after being part of such a thing would be the mark of a sociopath in my mind. These things go far beyond what most are even aware of.

To force me to do these things and then participate in the ensuing coverup is more than any government has the right to demand.
