I think it bears mention that Andres Raya, the topic of this post way back up at the top, was not suffering post-traumatic stress disorder, and did not commit suicide.
He was a gang member, he was high on cocaine at the time, and his Marine unit never even saw combat. Hell, he was getting transferred to Japan.

Andres was not an example of the horrors of war, he was an asshole turd who shot at cops.
