PTSD - it’s where the money is.
I've never served in,or near,combat so I can't speak from personal experience.However,my sister-in-law's father was a WWII vet and he had it.She didn't tell me,at least,the stories until after both he and her mother died.Nightmares...crying spells...fears.He was a great guy and managed to make a good living for his family but he did suffer...both in Europe and after he got home.
Do some guys try to scam the system? Probably.But if you're trying to claim that all such claims are phony I'll have you talk to my s-i-l.
Just sayin....
I would trade every dime if he could have not suffered for 40 plus years. What a jerky remark!
