That's not a possibility, if he was moving or even standing to sit down the odds of getting a hit decrease substantially and it becomes a shot that's not worth taking.
I would expect him to have been static, ie, either stood still or sat down and either drinking from a bottle or eating a sandwich or even on a mobile phone, even sat down the odds of getting a hit are lowered even further and very few snipers would risk a shot, no sniper is going to take risks, they're either certain of the hit or they don't take it.

That's just my opinion of course which around this forum I've noticed that its not worth much.

No, you're dead on here. The bullet would have arrived long before the sound would have (If it was even noticeable). The target would have had no warning at all, and would have just been standing there sipping his latte.

I assume that more or less the bullet travelled near the speed of sound. 3.5 kilometers, 10 seconds flight time: average speed 350 m/sec. Speed of sound: roughly 340 m/sec. The shot sound probably arrived at the target area 0.5 seconds after the target was hit, plus minus some tenths of a second.

The .50 BMG round is listed as traveling at 1200 m/s (EDIT: thats for the browning machine gun from WWI, the M107 Sniper rifle uses a .50 round that travels at 853 m/s), but there would be substantial losses in that velocity over the distance traveled resulting in the ten second flight time. Plus, I'm not sure if they were actually timing the shot to the tenth of a second, so I'd guess 10 seconds is just an estimate.

But regardless of the math, the bullet was supersonic initially, leading to it arriving long (relatively speaking) before the sound did.

But while the bullet travels in a "straight" (ignore ballistics) line, the sound travels in every direction. It is governed by the inverse square law. Where if you double the distance, the energy of the wave is now 1/4. Quadruple the distance, and it's 1/16 the energy. By the time it reached the target, it would have been barely noticeable. Especially in a location that distant gunshots are not uncommon, it probably wouldn't even have been noticed.

And ISIS aren't exactly a thinktank, so they probably thought that the sound was another shot coming at them

I admit, it was a nice shot. But in today's economy, we really need to do a little bit better than this guy did.

SAS sniper kills THREE ISIS fighters with a single shot during an operation in a remote Iraqi village



Quote:
A British sniper in Iraq killed three ISIS terrorists with one bullet in what has been described as a shot in a million.
The SAS marksman fired one bullet that killed two men instantly before it ricocheted into a third during a November mission in a remote northern Iraqi village.


The sniper fired his single .338 Lapua Magnum bullet from a L115A sniper rifle from a range of 1,800m just as the senior ISIS members prepared to fire shots into a crowd of women and children.






An SAS marksman fired one bullet and killed two senior ISIS members instantly before it ricocheted into a terrorists during a November mission in a remote northern Iraqi village (file photo)



A source told The Daily Star Sunday that the shooting happened during a covert SAS intelligence gathering as the troops monitored Islamic State-controlled areas while Iraqi forces advanced toward Mosul.
The SAS squad was tracking the IS members when dozens of women and children tried to flee from the extremists.
When the terrorists ordered the civilians to stop and pointed a machine gun at the crowd from a second-storey window, the SAS team decided they had no choice but to open fire and save the fleeing group.
The sniper, whose rifle was fitted with a suppressor to reduce noise, fired his once-in-a-lifetime shot.


The bullet first struck the man holding the machine gun in the head then hit a second terrorist in the chest. It passed through his body, ricocheted off a wall and hit a third man - who was in the same room - in the neck.
The source said the 'shot was one in a million' and added that he didn't believe it was planned.
'Alongside the sniper was an SAS spotter, who was watching the target through binoculars,' he said. 'The whole incident was over in a flash.'
The third man lasted for about 30 seconds before dying, while the others were killed instantly a source told The Star.

Iraqi forces launched in October a campaign backed by a US-led coalition to take back Mosul from the hardline Sunni group which captured the city in 2014, declaring from its Grand Mosque a 'caliphate' that also spanned parts of Syria. Mosul is pictured above on Saturday


'No one could quite believe what had happened,' the source added.
The SAS team entered the house following the shooting and confirmed that the three men were dead. They took fingerprints and photos of the scene before leaving by helicopter.
The Ministry of Defence told MailOnline that it does not comment on SAS activity.
Iraqi forces launched in October a campaign backed by a US-led coalition to take back Mosul from the hardline Sunni group which captured the city in 2014, declaring from its Grand Mosque a 'caliphate' that also spanned parts of Syria.
Mosul is the last major city stronghold under Islamic State control in Iraq.
Islamic State detonated explosives in the largest hotel in western Mosul on Friday, in an attempt to destroy it and prevent Iraqi forces from using it as a landing spot or base in their offensive to capture the city, witnesses said on Sunday.
The Mosul Hotel, shaped as a step pyramid, appeared to be leaning to one side after the explosions, said two witnesses contacted by phone, requesting anonymity as the militants punish by death those caught communicating with the outside world.
The Mosul Hotel sits alongside the Tigris river that cuts the city into two halves. The explosion comes as Iraqi forces appear about to take full control of the eastern side and prepare to attack the western bank.
We have to economize, gentlemen. The days of "one shot one kill" are over. We just can't afford the ammo costs these days. We need at least two kills for every round to make our projected ROI.

This very shot proves you wrong though.

A shot at over 1500m is never a certain hit, and that has nothing to do with the skills of the sniper team.
Too many factors play a role and at these ranges, a wind gust 1km from your current position can ruin it all, no matter how good your data is. The target also could have moved at any moment during the loooong time of flight, causing a miss.
And at 3500m? Jesus...

In the end this was a simple "why the hell not?" shot, resulting in what can be compared with a hole in one at golf. It can happen... But it has nothing to do with being certain.
They probably couldn't believe they actually did hit themselves for a moment. On first shot as well. Crazy!


Oh, fun fact: the bullet basically struck the target from above at this range due to ballistics. His buddies saw something they won't forget for a while...tehehe.
