Empire of the Sun is a film about civilians caught in a war zone.
The Things They Carried, by Tim O'Brien, is a collection of short stories about the Vietnam War. It shows the exhilaration, the terror, the cruelty and hardship of living through a war. It definitely doesn't glorify conflict.
My War Gone By, I Miss It So, by Anthony Loyd, is a firsthand account of the Bosnian conflict of the 90s. It is ugly and brutal, and the author tries to give an honest presentation of his own state of mind at the time.
Black Hawk Down (the book, not the movie), by Mark Bowden, is a fairly thorough account of the incident in Mogadishu in 1993. Bowden did a lot of research and describes the political background that led to the UN and US presence in Somalia, and all of the mistakes that led up to the helicopter being shot down and what happened after. He interviewed many of the military personnel who were actually involved and recounts the events from several different perspectives. And as the Wikipedia article says:
Bowden simultaneously manages to capture the siege mentality felt by both civilians and the US soldiers, as well as the broad sentiment among many residents that the Rangers were to blame for the majority of the battle casualties.
This is a very realistic presentation of what combat is like, framed inside the perspective of the overall military operation. Bowden doesn't shy away from describing the mistakes in decision-making, but also does a fair job of describing how lack of information or bad information leads to bad decisions in the moment which result in people dying for no good reason. He definitely doesn't glorify the conflict. My overall impression after reading it was "I hope I never have to be involved in anything like that".
And finally, Alice's Restaurant, by Arlo Guthrie, is a song about the draft.
if you wanna end war'n'stuff ya gotta sing loud
Everything old is new again.
