One Shot - One Kill by Charles W. Sasser and Craig Roberts. This book is a combination of personal accounts and research. The authors interviewed snipers from both the US Army and the US Marine Corps. The times covered are World War II, Korean War, Vietnam War, and the experience of the Marines in Beirut. Some of the chapters are the personal accounts of these snipers and other chapters are analysis of information the authors found in their research. It is a very interesting book for those interested in learning more about snipers.
Flags of Our Fathers is the story of the Marines who raised the second flag atop Mt. Surabachi on Iwo Jima for the photo that the journalist took. There was a flag raised before it but the flag was too small (according to the brass) and the journalist wasn't there the first time. The book is written by the son of one of the flag raisers. It gives a brief life history of each of the Marines and what happened to them after the war.
I don't know if the movie that comes out this October will cover everything in the book and how true it will be to the book.
