Rifleman James McKie, a 29-year-old British soldier, has been hailed as a hero after saving the lives of two others as he picked up and threw back a grenade which landed near them.
He said the grenade landed near the three men while they were situated on a rooftop in the Sangin area.
"I dived forward, picked up the grenade and threw it off the roof," Rifleman McKie said.
"I wasn't prepared to see another guy from my platoon get hurt, even if that meant I got hurt myself," he said.
The rifleman, who is originally from New Zealand, has been fighting in Sangin for the past five months.
The BBC's Caroline Wyatt spoke to him about the incident.
