This video is from a helmet cam of a helicopter pilot. It's been uploaded to Youtube so people can see what the war is like from a 1st person view. And it's in 720p hi-def!
The guy that uploaded this has uploaded tons of other vids too from the war. Presumably he's the soldier who filmed this stuff. It's all real cool. You should check out his Youtube channel http://www.youtube.com/user/FUNKER530/videos.
