During the 80th you could witness a lot of vets, who were blind, men who had lost limbs - quite common here. Not to mention rape for the women.
These folks shaped the daily live.

> Early in 1978, the diagnosis term "post-traumatic stress disorder" was first recommended in a working group finding presented to the Committee of Reactive Disorder
> The addition of the term to the DSM-III was greatly influenced by the experiences and conditions of U.S. military veterans of the Vietnam War.
Ham-fisted a film as it was, First Blood w/ Sylvester Stallone really launched the term into the American consciousness and completely changed the perception and sympathy towards Vietnam veterans. The DVD commentary is arguably more interesting than the movie.
You think nobody suffered PTSD before WW2? Look up the battle shock that people suffered in WW1.
Any question at the start of a reply can be answered with, "No, that's obviously not what they said, let's try to keep the drama to a minimum please."
