The T-69 II G is a Bangladeshi upgrade to their fleet of T-69 tanks (Type 69-IIM, industry code WZ121H), most likely inspired by the modifications performed by Pakistan as the Type 69-IIMA (WZ121K); these tanks underwent upgrades sometime between 2007 and 2009 with a new long-barrel 105 mm cannon, ERA packages on both the UFP and turret and likely FCS upgrades, especially for the optics. The tank was first seen in 2009 during the BDR mutiny. The upgrade served as an economic alternative to extend the service life of the Type 69 tanks. Later these tanks supported the newly bought MBT2000 tanks before T-59G Dujoy (Invincible; দুর্জয়) or VT-5 joined the army.

It was introduced in Update "Starfighters" as a premium pack in the Gaijin store. It was removed from sale after the 2022 May sale. The T-69 II G has since been briefly made available for purchase in-game with Golden Eagles for the 2022 and 2023 Chinese "People's Liberation Army Day" mini-events.

T-69 II G is an improved derivative of the Type 69, it is one of many Chinese tanks hailing from the lineage of the original Type 59, itself a version of the Soviet T-54. It has a few tricks up its sleeve and makes a good companion to the similar ZTZ59D1; while the kinetic protection or the mobility are not the best among other medium tanks/MBTs, the ERA packages will often save the tank from lower-tier chemical shells (HEATFS, missiles) while the high-velocity main cannon makes sure to make an impact on enemy targets. Players should be extra careful not to field the tank at the beginning of battle, as well as make sure to disable the enemy with the first shot, due to its inferior reload rate and reaction time.
