There's a two documentary that recreates and features interviews with
the snipers and spotters, explaining a lot of the stuff. That Canadian that is credited with the longest shot for instance, was
firing down from a mountain onto a ridge using Sun-heated US
ammo with a Canadian bolt-action .50. It took him 3 shots to
takeout a laden, but moving Taliban.
