The 28 year-old prince has just finished his five-month second tour of duty in Afghanistan. He said he fired at Afghans from an Apache attack helicopter.
Harry revealed this in an interview before he left Afghanistan on Monday.
He was seeking to justify his hostility towards Afghans while on duty in the southern province of Helmand.
The prince is back home after a five-month tour of Afghanistan as an Apache pilot gunner.
Prince Harry served a 20-week mission with NATO forces in the southern Helmand province. He was deployed to Afghanistan shortly after his scandalous nude pictures at a hotel in Las Vegas were published on the Internet, making headlines worldwide.
“Take a life to save a life. That's what we revolve around; I suppose…If there's people trying to do bad stuff to our guys, then we'll take them out of the game,” he said in an interview.
Earlier in January, former Afghan Prime Minister Gulbuddin Hekmatyar and an Afghan freedom fighter told The Daily Telegraph, “the British Prince comes to Afghanistan like a jackal to kill innocent Afghans while he is drunk.
At least 440 British troops have been killed in Afghanistan since the U.S.-led invasion of the country in 2001.
