Second your acknowledgement...astonishing feat.
And you forgot to mention that the sniper has got to be lucky enough to catch the target in a position that's not going to change within the 10 seconds it's going to take the bullet to travel; a bug or an itch could queer the deal.
Not to detract from the feat, though, I'm curious whether anybody knows how much of the sighting job was done by the scope, itself? Just the fact that it could zero in on a target at 2+ miles indicates that it's an awfully high-tech piece of equipment.
