Whoever got paid to be the technical expert on that film got overpaid.
Snipers don't shoot thousands of rounds per week. It's not an accuracy by volume event. It's a lot of field time, yes, but its more like jump in, walk around for two days, get set up, spend the next 36 hours not moving (did I just shit myself? I think I might have), make your reports (or radio them in throughout) then crawl home.
thousands per week? Nope.
