And at 650+ feet, a human being doesn't exactly rival Optimus Prime in size. I fail to see how an ACOG wouldn't be more than useful at such a range.

But when used in full auto and when your target is from the gates of the White House to the actual building itself, you might want to put those ACOGs on rifles than SMGs

The one eye sees the bright dot against the blurred target scene, so the brain picks the scene from the unaided eye. The shooter swings the weapon towards the target while perceiving the dot indicating where the weapon is pointed. As soon as the weapon begins to become steady in the target area, the brain switches to the magnified view.
