Chief Master Sgt. of the Air Force Kaleth O. Wright speaks during a congressional luncheon in honor of U.S. Air Force Tech. Sgt. John Chapman, in Washington, D.C., Aug. 21, 2018. Sergeant Chapman will be posthumously awarded the Medal of Honor Aug. 22, 2018, for actions on Takur Ghar mountain in Afghanistan on March 4, 2002. His 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 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. Rusty Frank)
