James R. Layton, 22
Layton, 22, died September 8 in Kunar province, Afghanistan. Layton rushed from his sheltered position with his first aid kit to help Marine 1st Lt. Michael Johnson, 25, of Virginia Beach, Va., who had been wounded in the enemy attack. Johnson and two other Marines died, as did eight Afghan troops and an interpreter. "This guy died a hero," said Cpl. Dakota Meyer, the Marine who retrieved Layton's body.
