Since we are at it, is there some other feature in the code that you are aware of?
For example do top attack missiles factor in that they will not hit top armor at a perfect 90°? Or is that left to OOB designers by means of lowering warhead penetration in the missiles themselves?
Stuff like that.
Top attack missiles get more top attack hits, and can do so from the same level as the target (unlike normal shells which have to be fired from higher up).
