The last civil war veteran passed when I was 8.
What is true for veterns then is true now.

today 180,000 of vets are homeless and wandering the street.
More troops have commited suicide since 2001 than have died from physical wounds.
2,456 vets have died due to not having health care insurance and access to treatment since 2006.

Vets get shell shock. Always have always will no matter what each generation calls it.
