It will allow us to optimise the penetration system and unify it for all high-calibre (APCR/HVAP) shells. At the same time, it will allow us to avoid situations in which data from various sources and countries is contradictory, since these sources were managed by various systems and penetration methodologies. We believe that the new system will be more transparent and easier for players to understand without sacrificing realism (as an example, in the USSR’s firing tables the data on penetration follows the same DeMarr formula, as do the calculations in AaG). Yet another advantage will be the ability to immediately get penetration data for any high-calibre or sub-calibre (APCR/HVAP) armour-piercing shell for which there is information about its muzzle velocity, falling speed, and mass. For AP/APC/APBC/APCBC shells we have also recalculated the effect of incline – the effect whereby the thickness of the armour being penetrated drops as the incline increases (the slope effect) when performing formula-based calculations in order to achieve uniformity and eliminate certain inaccuracies in their current values. As you can see from the examples below, compared to the current values for an angle of incidence of 30 degrees, penetration ends up increasing, and for an angle of 60 degrees, on the contrary, it drops. According to our evaluations, the role of proper tank positioning, i.e. placing the tank correctly in relation to the weapon being fired, will increase. Using this chart you can familiarise yourself with the formula for calculating the slope effect for AP/APBC/APCBC shells and the resulting slope effect values.

APCR/HVAP and APDS shells will get updated slope effects that will make it possible to more accurately factor in the technical characteristics of a shell’s construction that influence the penetration process. For APCR/HVAP shells the indicators for speed reduction will be ascertained based on the example of how this was done for APHE and APDS shells. The new system is so simple and productive that, if you know a shell’s individual attributes, you can calculate its penetration using the DeMarr formula on your own.

CALCULATE

Foreseeing questions about “historical accuracy” and correspondence with actual firing data, we should mention that the data used to calculate armour penetration figures are based on existing documents and is nothing out of the ordinary. Historical and technical accuracy will remain one of the key parts of the game, but the game environment cannot match reality exactly, so the values used for our calculations allow for a certain degree of conventionality.
