Stories: Iraq Diaries 'Reveille and Retreat'

Members of the Pennsylvania National Guard are citizen-soldiers. Usually, they leave their families and their jobs just once a month, for training. Now, the members of the 56th Stryker Brigade are about to deploy to Iraq. They left Pennsylvania in September for intensive training at Camp Shelby, Mississippi. As part of our audio diary series, Sergeant Jason Burrows records the distinctive sound that marks a soldier's daily life at the post. We also hear from Sergeant Nedrow about what that sound means to him.
