Marcus Luttrell, author of "Lone Survivor", has written his latest book "SERVICE: A Navy SEAL at War" about his own experiences as a combat-trained Navy SEAL and about the soldiers who give their lives to defend their nation and each other.  Still fresh from Operation RAMADI in Iraq and Operation REDWING in Afghanistan, Luttrell retired from the SEALs and began the turbulent transition back to civilian life, embarking on a quest to understand why a rare few choose to dedicate their lives to the protection of their country for a cause that is both abstract and deeply personal. Touring the country and connecting wiht veterans of all generations, he met with military from all service branches - Army, Navy, Air Force, and Marines - in the hope of making their stories known.

"SERVICE" spans the entire spectrum of modern U.S. Military history, from World War II to the present, and touches what defines our martial tradition, from West Point to the Naval Academy to the Guards at the Tomb of the Unknown Soldier.
