The designation is so treatment gets to Line Of Duty first both in the service and later on the VA. Combat injury with Purple Heart gets you highest priority IIRC. If you are low priority even with a more severe injury you likely will still have to wait till others are treated.

I heard he had mental/emotional problems prior to joining. Did anyone know if this is true? And does the military allow that? It cant possible be good to put an unstable individual in a stressful atmosphere.....especially if he is responsible for protecting the lives of others. It seems that would be grounds for disqualification.
