What is the longest range a sniper has shot from?

There is plenty to separate any elite sniper from a regular sniper.

One of them is the most extended range that a sniper has fired from, and with this said, Corporal Craig Harrison is the longest confirmed kill on record, with the killing of two Taliban's with consecutive shots for 2.67 kilometers which is 8120 feet in Helmand Province, Afghanistan in November of 2009.
