Breath is a Weapon Proficiency available only for Assault Rifles in Call of Duty: Modern Warfare 3.


It allows players to hold their breath while aiming down the sights, much like when aiming down the scope of a sniper rifle. This causes the weapon to cease swaying, making it easier to shoot enemy players at a distance.

Since this effect automatically occurs when using the Thermal Scope, it is not necessary to use in that instance.

The effect is only used for the first shot, and once that shot is fired, normal weapon sway and recoil patterns continue.
