The Merkava Mk.3 was developed in the late 1980s. The variant received a new suspension system, a 1,200 hp engine, a new transmission, and a new 120 mm gun developed by Israel Military Industries based on the Rheinmetall L/44. Serial production of the tank began in 1990. In parallel, the tank's design was constantly improved. In 1994, the Merkava Mk.3B modification was created, which received enhanced turret armour, an improved hull design, and other changes. A total of around 700 Merkava Mk.3 tanks in various versions were produced before production ended in 2002, and they continue to serve in the reserve forces of the IDF to this day.

Introduced in Update "Danger Zone", the Merkava Mk.3B boasts significantly more firepower than prior variants. As the first Merkava to be equipped with the potent 120 mm IMI L/44, which features an excellent APFSDS round, it delivers impressive destructive capability. The more powerful 1,200-horsepower Continental AVDS-1790-9AR diesel engine also significantly improves mobility over previous variants. This enables players to reach crucial positions considerably faster than before, allowing them to get into position first and gain a significant advantage in the fast-paced battles of modern warfare.
