Type 15 light tank (formally named ZTQ-15, referred to as Type 15 light tank for short), code named Panther, is a light tank equipped by the Chinese People's Liberation Army Army, which is another key main battle equipment after Type 99 main battle tank. The Type 15 tank is equivalent in weight to the old Type 59 tank, but has stronger firepower, mobility, and protection. It can carry out "frontline firepower assault" and is also known as the "lightweight main battle tank" by the outside world. Compared with the main force of the Chinese Army's Type 99 tank, the Type 15 tank has a compact appearance and light weight, making it suitable for use in the western plateau areas of China and the densely populated water network in the south.

The T-34/85 is a famous medium tank developed by the Soviet Union during World War II in 1943, based on the upgraded firepower of the T-34 medium tank. It is a new type of tank developed on the basis of the T-34/76. As the main tank model of the Soviet Union in the later stages of the war, it surpassed the T-34/76 in terms of firepower and armor. Compared with the Panther, the T-34/85 has lower firepower and armor, but its performance is reliable, its structure is simple, and it is easy to produce. Its total weight is lower than the Panther, and its overall combat capability surpasses that of German tanks, reaching the best level of the T-34 series.
