Or... their traumatic brain injuries are being ignored and dismissed by the powers that be as nothing serious... One should expect Uncle Sam to be as sympathetic to their wounded as, say, the NFL, right?
Funny story:
My friend's grandfather was a doctor back in WWII days. He didn't serve himself, but picked up some extra cash working at the local induction center alongside military doctors... giving physicals, doing evaluations, etc, you get the idea.
Part of the physical back then was inoculations for... well, Malaria, Tetanus, etc... you get the idea. He was shocked and livid when he noticed that, in order to save time and expenses, the military "doctors" were refilling and reusing the same syringes to inoculate each soldier in line. Enraged, he stormed the office of the supervisor, allegedly a medical man himself, and had to explain that a single sick soldier in the lineup would end up infecting everyone with anything from TB to Polio to the Black Plague.
The next day he received a message from the Army: They thanked him for his service, but it would no longer be required.
So, yeah... he developed a healthy skepticism of military efficiency from that day on... as did I after hearing stories like that one.
Possibly, and I have no doubt at least a few of them were.
