London, February 3 (RHC)-- A British Royal Marine has been dubbed the world’s deadliest sniper over his scores of fatal hits in Afghanistan. The unnamed Marine recorded most of his 173 confirmed kills during tours of Afghanistan in 2006 and 2007, The Sun reported.

The Briton reportedly served in the Royal Navy's elite unit for more than a decade. He served both in Afghanistan and Iraq. He is said to be married and father of two from southern England.

“He took no satisfaction in the job he had to do. Because he saw the enemy as humans he has not struggled emotionally or psychologically with what has happened,” the British daily quoted an unnamed source as saying.

According to the Sun, the British sniper hit 90 Taliban militants in one stronghold in just one day. If the figure of 173 kills is proven true, the sniper is more deadly than U.S. Navy SEAL commando Chris Kyle, who had 160 confirmed kills, making him the most lethal U.S. sniper.
