Joe Haldeman is a great writer. His novel, The Forever War, is an amazing piece of satire on the Vietnam War, comparable to Catch 22. It happens to be science fiction, but if you don't read SF don't let that stop you. You'll be missing out.
I heard that Joe will be in a documentary on Iraq war veterans on April 16 on PBS. It's called "Operation Homecoming" (part of the series "America at a Crossroads") and it tells the tale of the war through the words of soldiers. The trailer is on YouTube, and it looks to be a powerful show.
Joe is a veteran of Vietnam Nam, and much of his work is based on his experience there. His writing influenced me when I was in high school, and I got a chance to meet him once or twice at conventions and such. He's a good guy (and his wife, Gay, is maybe even nicer than he is, which is saying something). Someday I'll write a good, detailed name-dropping post about them. It's a funny story.
But anyway, I'll be watching "Operation Homecoming" if I can. It really does look very good.
