The Ballistic Calibration is an attachment featured in Call of Duty: WWII, unlocked by achieving weapon level 2 with sniper rifles. It functions similarly to the Ballistics CPU in previous games as it reduces the idle sway when aiming with a sniper rifle. It does not affect rifles equipped with the 4x Optic or the Iron Sights attachments.
