Oh it is real. Its just ballistics. Mass x Energy. The sniper is using a 50 caliber rifle. A 50 cal. round is about 7-8 inches long and the casing is about an inch in diameter. The bullet itself is one-half inch in diameter and roughly one and one-half inches long. When a bullet that big and has enough enery to travel 1.5 miles and it hits something it explodes.
I have seen it in person on a smaller scale.
It is just a display of incredible marksmanship.
