The ability to add a vehicle class to a tank / the ability to create tank branches yourself

I think there’s no point in explaining the idea behind adding a vehicle class. As for the branches, the idea is that we could arrange the tanks one after another, forming progression trees. We could also add a function for assigning experience points for researching tanks and purchasing them with silver

我认为解释添加车辆类背后的想法是没有意义的。 至于树枝，我们的想法是我们可以一个接一个地安排坦克，形成进展树。 我们还可以添加一个功能，用于分配研究坦克和用银购买它们的经验值。
