Absolutely. And those who are less that skilled enough to syuch levels of performance are better equipped with bullet hoses and carrying lighter weapons and more ammunition, or using underbarrel grenade launchers.
But so long as any of our potential adversaries may be equipped with a weapon capable of 1000-yard hits...or a usable beaten zone from a thousand meters' distance, we had better have an effective means of replying in kind available to at least one dedicated high-performance rifleman per squad or platoon, probably teamed with one of those grenadiers or light machinegunners.
And that's even more so in city and urban operational areas, where cover and concealment may offer shots at much closer ranges, but require very precice bullet placement at those urban distances during MOUT.
