A Canada special elite forces sniper broke the world record for the longest kill shot in the military history. According to the Globe and Mail, the sniper whose name was withheld, fired from a stunning distance of 3,450 meters. He is a part of the Joint Task Force 2 in the Iraq Civil War.
The target was an ISIS operative and by killing him, the sniper broke the previous record by almost 1000 meters. He stood on a high-rise during an operation that took place within the last month in Iraq and fired. It took the bullet under 10 seconds to hit the target. The report said that the kill was independently verified by video and camera data. An unnamed military source was quoted saying: “Hard data on this. It isn’t an opinion. It isn’t an approximation. There is a second location with eyes on with all the right equipment to capture exactly what the shot was.”
