Retired 1st Sgt. Keith Melick (right) and retired Army Special Forces Command Sgt. Maj. Roy Wilkins (left) were on a mission in Kandahar Province in Afghanistan in 2004 when their caravan was hit by an IED.

Roy was seriously injured in the blast, but was pulled from his Humvee and survived.

Ten years later, Roy was at a VA medical center gym when he heard a familiar voice—one he recognized from the day of the explosion. The voice belonged to Keith, the medic who’d pulled him from the wreckage. That chance reunion marked the beginning of a deep friendship.

At StoryCorps, Roy and Keith talk about their memories of both encounters.
