The soldier is said to have killed the militant – who was attacking Iraqi soldiers – from a tower block in Iraq.
He used a McMillan TAC-50 to fire the bullet, which took 10 seconds to reach its destination 11,319ft away.
The exact date that the shot was fired hasn’t been confirmed, but it’s believed to have happened within the last 30 days.
A military source told Canada’s Globe and Mail newspaper that the soldier was from the elite Joint Task Force 2.
The paper quoted the source as saying: “The shot in question actually disrupted a Daesh [Islamic State] attack on Iraqi security forces.
“Instead of dropping a bomb that could potentially kill civilians in the area, it is a very precise application of force and because it was so far way, the bad guys didn’t have a clue what was happening.”
Considered the longest kill in military history, it has been independently verified by video footage.
The previous holder of the ‘longest confirmed sniper shooting’ record was a British soldier, who killed from a distance of 8,120ft – about a mile-and-a-half – during an operation in Afghanistan in 2009.
Third and fourth on the list of celebrated shooters are also Canadians; Canada’s snipers are considered among the best in the world.
