A deadly accurate 20-year-old British sniper in Afghanistan managed to kill six Taliban insurgents with just one bullet, The Telegraph reports.

The marksman, a Lance Corporal in the Coldstream Guards, apparently hit a suicide bomber’s trigger switch from 930 yards, causing an explosion that killed him and five of his fellow terrorists.

Lt. Col. Richard Slack outlined what exactly happened in an interview with The Telegraph:

“The guy was wearing a vest. He was identified by the sniper moving down a tree line and coming up over a ditch,” said Lt Col Slack. “He had a shawl on. It rose up and the sniper saw he had a machine gun.

“They were in contact and he was moving to a firing position. The sniper engaged him and the guy exploded. There was a pause on the radio and the sniper said, ‘I think I’ve just shot a suicide bomber’. The rest of them were killed in the blast.”

It is understood the L/Cpl was using an L115A3 gun, the Army’s most powerful sniper weapon.
