When Frank Johnson arrived in Vietnam in 1969, he was 19, a young soldier untested in combat like thousands of others - but with two important differences: Johnson volunteered for the elite L Company Rangers of the 101st Airborne Division, a long range reconnaissance patrol (LRRP) unit, and he kept a secret diary, a practice forbidden by the military to protect the security of LRRP operations. Now, more than three decades later, those hastily written pages offer a rare look at the daily operations of one of the most courageous units that waged war in Vietnam.

From 1999 to 2009, U.S. Navy SEAL Chris Kyle recorded the most career sniper kills in United States military history. The Pentagon has officially confirmed more than 150 of Kyles kills (the previous American record was 109), but it has declined to verify the astonishing total number for this book. Iraqi insurgents feared Kyle so much they named him al-Shaitan ("the devil") and placed a bounty on his head.
