A sniper has earned a place in military history by killing an Islamic State jihadi from more than two miles away. The elite Canadian soldier took out the fanatic from a high-rise building during an operation in Iraq last month, it emerged yesterday. He was so far away that the bullet took almost ten seconds to reach its target. A military source said the shot was taken during an IS attack on Iraqi forces. The soldier was 2.1 miles, or 11,614ft, away from the jihadi, beating the previous British-held record of 1.5 miles. The bullet from the rifle travelled at an eye-watering 792mph - faster than a Boeing 737 - and took ten seconds to reach its target The sniper, who cannot be named for security reasons, is part of Canada's Special Forces, assisting Iraqi forces in the war against IS. 'The shot in question actually disrupted a Daesh attack on Iraqi security forces,' a military source told Toronto's Globe and Mail newspaper. The source added: '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 away, the bad guys didn't have a clue what was happening.' The source described the difficulty of the shot, explaining that the sniper had to account for wind, ballistics and even the Earth's curvature. A military insider said: 'This is an incredible feat. It is a world record that might never be equalled.' The soldier used a McMillan TAC-50 sniper rifle – so powerful it can shoot through walls. It is designed to be effective only up to 1.2 miles. The Canadian sniper worked with a spotter, whose job is to help get an accurate shot. Spotters use binoculars and can see the target more clearly than the sniper, who uses a scope. Spotters carry a machine gun in case the militants discover their position. The pair will sometimes watch their target for hours. The spotter is essential because he keeps the sniper up to date on the location of the target and specific details. The sniper fires after exhaling for seven seconds – or until their lungs are empty and they are at their calmest. The elite Canadian sniper was so far away that the bullet took almost ten seconds to reach its target and was travelling at 792mph Then they fire and inhale immediately. The spotter will immediately inform them if they have hit the target. If they have missed they have a few seconds to quickly adjust before they are noticed and can try to hit the target again. The Canadian shooter is part of Joint Task Force 2, which deals with counterterrorism, sniper operations and hostage rescue. Last night a military spokesman said the task force did not carry out patrols with leading combat troops but was there to 'enable the Iraqi security forces who are in a tough combat mission'. The spokesman said: 'This takes the form of advice in planning for their operations and assistance to defeat Daesh through the use of coalition resources.' The sniper took the title from Briton Craig Harrison, who killed two Taliban machine gunners from more than a mile and a half away in November 2009. The Canadian Special Operations Forces Command confirmed the new record-holding sniper 'successfully hit a target' from 11,614ft away, beating the previous target by 3,494ft. Corporal Harrison was using the Army's most powerful sniper weapon, the British-built L115A3 long range rifle. It took six seconds for him to find out if his shots were successful. The Household Cavalry veteran opened fire after his commander and Afghan soldiers were attacked during a patrol in Helmand Province.

Bullet dropped from the guns plane 320" or more than 27ft. There is a lot of calculating going on.
Yeah. But that's what dope cards are for. The coriolis effect has to be factored in after about thirty-three hundred yards. And 792mph is getting close to subsonic. But the toughest part of the shot, imho, was finding a target that would sit still for the ten seconds it took for the bullet to find him.
Or you lucky enough that they move right back to the spot in 10 seconds. You think his buddies freak after seeing him explode and 10 seconds later hear the shot! LOL
Not quite that dramatic. : ) This bullet at 792mph was flying just a bit faster than the speed of sound (767mph). So they would have heard the shot less than a half-second after their fellow-terrorist went all squishy. Probably more like a quarter-second. Hmmmm...interesting. 11,614ft ÷ 1125 feet/second (speed of sound) = 10.3235 seconds (for the sound wave to arrive) (792mph × 5280ft) ÷ 60minutes ÷ 60seconds = 1161ft/second 11,614ft ÷ 1161 feet/second (speed of bullet) = 10.003 seconds (for the bullet to arrive) So it took the bullet 10.003 to travel that distance. Yet the article says it took just under 10 seconds. Hmmmm...maybe I missed something, eh? Anyway, the bullet was traveling at 1161 ft/second and the speed of sound is 1125 feet/second. So over a time span of 10 seconds, the bullet would gain 36 feet/second over its sound wave, making the bullet arrive in 10 seconds and the sound of the gunshot arrive .3 seconds after. Anyway, I was curious and those are my numbers. Anyone see a mistake? Certainly, I am no expert. Perhaps I am off but not by much (I hope).
I thought the sound wave travelled with the bullet. Meaning if you're on the receiving end, you hear the crack of the bullet followed by the gunshot.
I think there is some confusion there,but I may be wrong. Having been on the receiving end of sniper fire,I can tell you that you can hear the bullet "pop" as it passes by your ear,but I never once heard the gunshot. Maybe the sniper was using a silenced weapon,but I THINK they were pretty rare on Soviet weapons in 69. Could it be the guy that told you that heard the "pop" of a near miss and thought it was the sound of the muzzle blast? That was one silent goober after he took his shot and missed. He never tried another one. Good thing for him,too. I was plenty pissed because it made me drop my last chocolate bar in the stream I was crossing,and I would have had some fast movers drop some napalm on his ass if he had shot again and I could have located where he was.

I wonder if you would even hear the gunshot at over 2 miles away. You almost assume it had to be dead still (if the shot wasn't total pure luck). So a windless day in the desert, a fairly loud and powerful gun, maybe you would hear the gunshot at 2 miles pretty easily but it wouldn't be very loud. I'd have to look up some math on how sound dissipates over distances. I think you'd hear a mild thud in the body, probably with some blood spatter, then a slightly louder popping sound from the gunshot .3 seconds later. You can see I like imagining the effect of this "shot heard round the world" on the barbarian sand-rat and his buddies. We have no idea how loud the gunshot was when the bullet was fired so we can't do a very good estimate of how loud the gunshot would be when the jihadis heard it, .3 seconds after they see their jihad buddy start oozing a lot of blood. The sound intensity drops very sharply after only about 30 feet (sound intensity will decrease by the inverse square of the distance). The decibel level drops about 6dB each time the distance from the gun doubles. 73dB would be a pretty sharp pop, an unmistakable gunshot sound.

Again, I could be wildly wrong here, assuming the sniper rifle might emit sound at 140dB from five feet away from the gun barrel (a real loud cannon of a gun/bullet combo) and then dropping to 74dB at 10240 feet, meaning at 11,614 feet it would still be at least 73 dB. I think. Don't quote me for God's sake. LOL distance
