You are not allowed to "know" any of the game's formulae - as part of the agreement with SSI releasing the code to us.

In any case there are no "formulae" that can be written down in any simplistic set of shift tables for old fashioned tabletop or paper-shuffler warganes. The "formulae" are code in many different interlinked subroutines, which you would have to examine in toto.

Basically - if the penetration value shown is equal to or exceeds the defence value there is a chance of penetration. Over-penetration aids it, and so does larger warhead size. If penetrated then other functions are called to see what the shell does inside the vehicle, with WH size being a key component here...

Add in the many points where random choices are made - and there is no way you can say exactly what will happen when 2 bits of metal clang together. As in real life.

So - use your experience to judge whether a particular shot is worthwhile. Once you have a few hundred battles under your belt you will know if opening fire with Gun X against tank T at range R is worth your while - or not. (Use APCalc as a first approximation perhaps, but its only a guide and for 0 degree impacts).
