This episoderecounts Lance Corporal Kyle Carpenter’s actions on November 21, 2010, at PB Dakota in Helmand Province, Afghanistan, when a grenade came over a wall and he moved toward it, covering it to protect fellow Marine Nick Eufrasio, suffering catastrophic wounds and surviving after multiple resuscitations. The story traces the roots of that split-second act through Carpenter’s upbringing in South Carolina, early models of leadership and follow-through, boot camp at Parris Island, and combat losses in Afghanistan, arguing that what a person does without thinking reveals who they are. It then highlights Carpenter’s recovery at Walter Reed through more than 40 surgeries and frames leadership lessons for any leader around character built in ordinary choices, bearing under pressure, purpose as a decision, and caring for people as human beings.
