If you are interested in modern day warfare, check out the movie Bravo Two Zero, its a low budget flick, but its a good portrayal of modern day SAS combat, if you havent heard of Bravo Two Zero then theres something wrong with you

Also a good read is Immediate Action, The One that got away and Black Hawk Down. Black Hawk Down is an extremely good read, its about the hostilities at Mogadishu in Somalia back in 1993 when US Rangers and Delta Force had to fight for their lives against an overwhelming pissed of Somalian city, it's very indepth and sucked me right in, I couldnt put it down. Read this book if you havent already. It's awesome. And it's about Rangers, what more could you want.
