Very little new info today. Storm provided only one explanation:
今天新消息很少。Storm只提供了一条解释：

When a 120mm shell it hitting a 40mm side armor + 25mm track armor, the armor thicknesses do not add to one another when it comes to the three caliber rule: the rule is checked for each layer separately (which means that in this case it applies to the side armor)
当一发120mm口径的炮弹击中了一个40mm侧面装甲+25mm厚的履带时，在判定三倍口径碾压的时候装甲厚度是不会加在一起计算的：每一层都会进行一次单独的计算（也就是说在这种情况下炮弹依然会依靠三倍碾压的规则强行击穿40mm的装甲，而不是把两层算在一起的65mm）

There’s also one more picture of the AMX 50 120 changes for size comparison:
还有一张关于AMX 50 120的大小比较的图片：
