This HBO documentary chronicles the lingering effects of combat stress and post-traumatic stress on military personnel and their families throughout American history, from the Civil War through the conflicts in Iraq and Afghanistan. It shares the personal stories of soldiers through letters and journals, photos and combat footage, and first-person interviews of veterans of WWII, the Vietnam War, Operation Desert Storm and Operation Iraqi Freedom.
The mother of one of the featured soldiers has a blog. Please take a look if you're interested in what happened to Cpl. Nathan Domingo.
