I just recently watched a Korean war doc based on the chosin reservoir and it is honestly one of the best documentaries I have ever seen. It is 2 hours long and the Vets stories are incredible. They are so good and so well told you do not need war footage to appreciate what they are saying. They get down to the full grit of it.

Expectable stories about the chinese human waves and bodies piled 5 feet high.

Marines using the bodies of their enemies and dead buddies as sandbags.

"Whenever an American fired his weapon, a Chinaman died, nomatter where his weapon was pointed"

I watched this on netflix.com, they have a free 1 month trial.

Title: Chosin made in 2010

It is an awesome Docu.
