Journalist and best-selling author Sebastian Junger discusses his book, *War*, an account of his time with a US Army platoon on the battlefields of Afghanistan. They were collectively known as "The Rock." For one year, in 2007--2008, Sebastian Junger accompanied 30 men--a single platoon--from the storied 2nd battalion of the US Army as they fought their way through a remote valley in eastern Afghanistan. Over the course of five trips, Junger was in more firefights than he could count, as men he knew were killed or wounded and he himself was almost killed. His relationship with these soldiers grew so close that they considered him part of the platoon, and he enjoyed an access and a candidness that few, if any, journalists ever attain.
