Hello warriors,
大家嚎，

a new vehicle appeared on the supertest – a tier 10 Chinese event medium tank, 121B. Basically it’s the 121, only with 105mm L7 gun (British top medium gun) and 130mm hull front. There’s no way to confirm whether this vehicle is historical or a fake, but there’s a description.
超测服上出现了一辆新车—10级的中国活动用中坦，121B。基本上来说就是个121，插了个105mm L7炮（英国的顶级中坦炮），这面车身厚度变成了130mm。现在没有办法来确认这个车到底是史实的，描述如下：

This is most likely a Clanwars vehicle.
估计是个领土战的车。

描述：

121B is the a modernized variant of the “121” Chinese medium tank, developed in the sixties. Compared to the prototype, the 121B had more modern 105mm rifled gun, improved suspension and improved frontal armor. The vehicles of this type were equipped with IR lamps and laser rangefinder. Thanks to the optics used on the 121B the tank had very high accuracy on the move compared to the Type 59.
121B是在上世纪60年代对中国的“121”中坦进行的一次现代化改修的产物。与原型车相比，121B上装了一杆更加先进的105mm线膛炮，悬挂和正面装甲都有了增强。这种车上加装了红外线灯和激光测距器。感谢121B上使用的光学瞄准系统，它的移动时精准比59式要好很多。
