How do you get PTSD from a non-combatant billet?
It happens. Hazing, survivor guilt, third party trauma, etc. A drill instructor could have yelled at her. Or even possibly suffering a real personal trauma. So it was and is a legitimate question.
That's why I've argued since the murder of Chris Kyle that veterans getting PTSD shouldn't be allowed to own firearms. And if this crazy is getting PTSD disability, maybe driver's licenses should be restricted as well
