About Sean Parnell

Decorated Combat Veteran, NYT Best Selling Author, Father, Leader

Army Ranger, combat infantryman with the elite 10th Mountain Division, and veteran of 485 days of fierce fighting along the Afghan-Pakistan border, Captain Sean Parnell’s unique leadership skills, welded his platoon into one of the most fierce and effective American fighting units in modern military history. Repeatedly outnumbered and outgunned by a foe whose avowed purpose was to overrun his platoon, Sean’s “Outlaws” battled furiously in the most rugged terrain on the planet—the towering Hindu Kush Mountains. Eighty-five percent of his platoon received Purple Hearts for wounds incurred in battle, but his men gave far more than they received. Outlaw Platoon killed over 350 enemy fighters in some of the biggest firefights of the Afghan War. His platoon remains one of the most decorated Army units since 9-11.

Sean was wounded in action on June 10, 2006, when his platoon was nearly overrun, for the first time, by a force that outnumbered them almost ten to one. Refusing to leave his men as they battled the enemy at point-blank range, Sean was knocked unconscious and wounded two more times during the firefight. Each time, he returned to his feet to lead his men again. His selfless example prompted one of his Soldiers to remark later, “Sean Parnell saved us all.”

After the June 10, 2006 battle, Sean continued to suffer from untreated head and neurological wounds. For weeks after, cerebral-spinal fluid leaked from his ears and nose while he continued to patrol with his men. His dedication to his men came at great personal cost: when he returned home following the 06 deployment, his wounds forced him from the army, and he was medically discharged.

Sean retired a highly decorated Captain and was awarded two Bronze Stars, one for Valor, and the Purple Heart.

Since leaving the Army, Sean has penned the New York Times best-selling book, Outlaw Platoon, which is the story of his platoon’s crucible of combat in Eastern Afghanistan. He is a subject matter expert on Afghanistan, the insurgency we face there, leadership, and how to use it to inspire and motivate men and women to achieve common objectives.

As co-founder of the American Warrior Initiative, an organization that inspires people to give back to our nation’s veterans, Sean has quietly become one of America’s most influential advocates for our military. Sean worked to pass the Veterans’ Access to Care through Choice, Accountability, and Transparency Act of 2014, which later became the Mission Act and signed by the President, as well as helping to get the VA Accountability Act passed out of the U.S. House of Representatives, in 2015.
