I have been watching Generation Kill, a seven part mini-series by HBO. It follows the Marines of the First Recon Battalion as they battle their way through the first 40 days of the Iraq war.
Generation Kill is based on the book by Rolling Stone writer Evan Wright, who spent two months embedded with the First Recon Marines. A lot is covered, so much so that maybe some of it might seem trivialized, but it makes for some pretty interesting television. If nothing else it'll give you some idea why, almost six and a half years later, the U.S. is still mired in Iraq.
I should caution that it's not for the faint of heart. There are some pretty graphic images, lots of colourful language, racism, homophobia, sexism..., and that's just amongst the Marines themselves!
