I am currently reading Horse Soldiers by Doug Stanton. It's an amazing story about a 12 man SF Team that goes into Afghanistan after 9/11 to hunt down the Taliban responsible for the attacks on America. So far it's a great book for anyone that enjoys reading about the US Army Special Forces.
Black Hawk Down the movie is based on the book written by Bark Bowden. It's based on a true story about young Rangers and Delta Operators fighting side by side in Somalia. As great as the movie is, I highly recommend to read the book as well.
