Question is title.
For example, Muton armor has a value of 28, and there is a 60% modifier to AP ballistic type damage. If an AP shot rolls 50 when it hits the armor, how much damage does the Muton actually take?
Would the calculation be (50damage-28armor) multiplied by 60%=13.2 damage?
Or would the calculation be (50damage multiplied by 60%)-28armor=2 damage?
I would guess the first calculation, but I don't really know.
