Secretary of the Air Force Heather Wilson speaks at Master. Sgt. John Chapman’s name unveiling ceremony at the Air Force Memorial in Arlington, Va., Aug. 24, 2018. Chapman was posthumously awarded the Medal of Honor for actions on Takur Ghar Mountain in Afghanistan March 4, 2002. An elite special operations team was ambushed by the enemy and came under heavy fire from multiple directions. Chapman immediately charged an enemy bunker through thigh-deep snow and killed all enemy occupants. Courageously moving from cover to assault a second machine gun bunker, he was injured by enemy fire. Despite severe wounds, he fought relentlessly, sustaining a violent engagement with multiple enemy personnel before making the ultimate sacrifice. With his last actions he saved the lives of his teammates. (U.S. Air Force photo by Staff Sgt. Chad Trujillo)
