The T-84, also known as the BM Oplot, is a Ukrainian main battle tank first produced by the KMDB plant in 1995. The T-84 is based on the modernised Soviet-era T-80UD tank (also designed and produced by KMDB), with the main difference being the use of a welded turret in place of the cast turret of the T-80UD, reinforced with two layers of Nizh ERA on the turret face and the frontal half of the sideskirts, as well as a revised powertrain to significantly increase the tank’s reverse speed and mobility. The T-84 has served as Ukraine’s main battle tank since its introduction in 1995, with several variants developed for both domestic use and export. The BM Oplot-M is the current production model of the T-84, introduced in 2009. It features an improved armour layout, a new electronic countermeasure system, and the PNK-6 panoramic tank sight.

In 2015, the Pakistani Army began its procurement programme to replace its ageing tank fleet. Two tanks were submitted: the VT-4 from China and the BM Oplot-M. After two years of evaluation, the Pakistan Army chose the VT-4 as its next standard MBT in 2017 and later secured a licence-production contract for the tank. Despite this, Pakistan also signed a memorandum of understanding with Ukraine that same year to upgrade its existing T-80UD fleet.

The Pakistani BM Oplot-M was introduced in Update 2.51 "Spearhead" in the Chinese ground forces tree and is identical to the Thai Oplot-T in the Japanese ground forces tree. The Oplot-M’s most noticeable feature is its remarkably fast reverse speed of 32 km/h—a unique characteristic that sets it apart from other Eastern Bloc MBT designs, allowing it to retreat and reposition more quickly. In terms of protection, the Oplot-M features multiple layers of ERA, NERA, and an electrical APS to protect its crew of three from harm. The main drawbacks of the Oplot-M are its underwhelming gun with a poor depression angle and several exploitable weakspots, such as the gap between the sideskirts and the hull.
