A powerful story of war in our time, of love of country, the experience of tragedy, and a platoon at the center of it all.

This is a story that starts off close and goes very big. The initial part of the story might sound familiar at first: it is about a platoon of mostly 19-year-old boys sent to Afghanistan, and an experience that ends abruptly in catastrophe. Their part of the story folds into the next: inexorably linked to those soldiers and never comprehensively reported before is the US Department of Defense's quest to build the world's most powerful biometrics database, with the ability to identify, monitor, catalog, and police people all over the world.

First Platoon is an American saga that illuminates a transformation of society made possible by this new technology. Part war story, part legal drama, it is about identity in the age of identification. About humanity - physical bravery, trauma, PTSD, a yearning to do right and good - in the age of biometrics, which reduce people to iris scans, fingerprint scans, voice patterning, detection by odor, gait, and more. And about the power of point of view in a burgeoning surveillance state.

Based on hundreds of formerly classified documents, FOIA requests, and exclusive interviews, First Platoon is an investigative expose by a master chronicler of government secrets. First Platoon reveals a post-9/11 Pentagon whose identification machines have grown more capable than the humans who must make sense of them. A Pentagon so powerful it can cover up its own internal mistakes in pursuit of endless wars. And a people at its mercy, in its last moments before a fundamental change so complete it might be impossible to take back.
