It is rocket science. His spotter was doing the science while an outstanding shooter pulled the trigger and their was a large helping of god given luck. At that distance even if he did not hit the target it scares the sh-t out of the bad guy. The bad guy thinks he is just a few hundred meters away and not two miles. It affects his actions and judgement greatly! Good shooting Mr. Canuck. Your lot have a good track record at long range kills. Thank you for your skills. You boys are good.
Hell, I’ve hit targets that far away, of course I was shooting from a tank with a 105......but still.
