Weird definition? ? AA allows the reticule to stick to the target ..thats the drag..if you just use horizontal motion with no AA you'll just slide past the target AA is what allows the reticule to stick to the point you want to hit ..you are moving the reticule sideways ..yes.. but you stick to the target because of AA..just moving horizontally is useless without the AA you wont hit anything without that target lock point fr I m AA
