Where to shoot?

merig00: Auto-aim aims at the center-mass (relatively) so usually you will hit somewhere around the turret. Each tank is unique in it's hitboxes. Take a look at these pictures http://forum.worldof...and-schematics/
Also notice that your aim triangle inside the circle changes colors when you aim at the enemy.
Green - you will penetrate
Yellow - might or might not penetrate
Red - will not penetrate
