The Leopard 2A4 and T-72B are both mass produced MBTs, with the leopard 2 featuring the widespread Rh-120mm smoothbore cannon. The simiulation presents a ~1987 engagement scenario, with the impact of a DM33 APFSDS on the upper plate, from a range of ~1.5km, at a point where there is a gap in the ERA (such as around the towing eyes). It should be noted that impacting the ERA would have little effect on the result as it is Kontakt-1 which was designed to counter shaped charges, not APFSDS.
This simulation does not represent a modern engagement between a Leopard 2 and a T-72, as both have improved greatly in firepower and protection, since the 80's
The performance of DM33 was purely derived from a Lanz-Odermatt calculation based off the diagram linked below. At 1500m the 1537.5m/s velocity was determined from a 75m/s drop over 1000m value given online (1650m/s muzzle velocity). At this velocity, the resultant LoS perforation against a 270BHN plate at 68° is 531mm (199mm thick plate). The plate is almost at the limit of penetration, aligning quite well with live-fire testing of 3BM32 Vant on Tankograd (195mm perforation limit failed to breach the plate). This gives the mass effectiveness of the armour at around 1.18, which is also close to the cited estimated value.
