my nephew went to Afghanistan as a medic, I said “you will never be the same” I was right
God Bless your nephew, and please thank him for his service.
My brother was in Vietnam '66-'67 with the 25th Infantry Division. He was a completely different person when he came home, mentally, and physically. He died in 1995 at the young age of 51 from a massive heart attack. Left a widow and four kids.
