Sad.
I know I'm going to get flack for saying this, but it's true; I've lived it. The enlisted ranks of the military are not America's cream of the crop youth. There are a few gung-ho patriots who could have gone to college or had some other opportunities, but by and large, it's kids that didn't see another option. Which means they may have had little support from family, lived in relative poverty, didn't do well in school, etc., before they joined. When they're discharged, nothing's changed. Now pile on top of it PTSD. Shit deal.
I'm not sure what to do about. I do think that, if problems are identified, these guys should have their enlistments extended and have the military try to deal with them, rather than the VA. If fact, maybe the VA shouldn't exist. Maybe the DOD should take care of veterans themselves. Combat veterans, anyway.
