ADS stands for "Aim Down Sights" in Call of Duty. It is the action of zooming in with your weapon, lining up your Operators eye with the optic or iron sights that sits on top of your current weapon, and boosting your accuracy. ADS is activated by pressing and holding the left trigger, right mouse button, or the respective touchpad on your mobile device. It is an essential mechanic in every Call of Duty game, as it allows players to be more accurate when firing their weapon, but it decreases movement speed and often field of view as a result. ADS speed is one of the most important stats for guns in COD Mobile, and most of the best loadouts will utilize ADS speed. Players can choose between ADS and HIP in the Control section of the settings for each class of weapons.
