The T-72B3 (Object 184M-3) is an up-gunned and armoured modification of the T-72B, which is the third variant of the T-72 main battle tank family. To simplify supply lines, old stocks of T-72B variants held in reserve were upgraded with components used in the new T-90 main battle tank family in 2010. The modernisation program (as the T-72B3M; post-2016 production) focuses primarily on the implementation of a new fire control system, in addition to performing an extensive upgrade on every tank, such as more powerful V-92S2 engines, a new steering system in the driver's compartment, and new universal, twin-pin tracks. While the tank commander's sight retains an upgraded version of the legacy TKN-3MK sight, the gunner's sight now has access to thermal imaging equipment as well as the new PNM Sosna-U panoramic multi-spectral sensor, which is a multi-channel, panoramic sight with a built-in laser rangefinder.

Introduced in Update "Raining Fire", the T-72B3 provides players with cutting-edge technology. With the much-needed thermal imaging equipment for the gunner's sight, players will be able to easily spot enemies from a distance. While all of these improvements do not eliminate its main flaw, which is the extremely slow reverse speed, they do make this tank one of the most powerful members of the T-72 main battle tank family to date. Players will be pleased to have this tank at their disposal, as it will undoubtedly perform well in battle.
