1 - Front Gun, 2 - Second Gun, 3 - Sam Battery, 4 - Ai guns on. Ai turrets will target aircraft once they are within 3 miles. You have to shoot the guns though. The guns on the first and second turret are at a slant because if they were normal, you would have trouble targeting surface vessels because there is a quite large snap-to-middle thing on the mobile sliders on the side of the screen, this makes it nearly impossible to precisly aim them. I did NOT write the funky trees script for the ai turrets, that was created by 232287168147825 (hope I got that right) I took the script from his Autoleading AA Turret, all credit for Funky Trees script goes to him.
