Im playing the dutch campaign and have to say the same thing has carried over from SF1, im suprised no one has mentioned it.
The dutch GILL ATGM is completely broken. I havnt done the maths but im getting less than a 10% hit rate in all my launches. The missiles constantly over shoot the target and drop 50-100 meteres behind the target. We use that ATGM in my unit and although it depends alot on the users skill its nowhere near a less than 10% impact weapon.
