Addition to the vanilla tank's weapons (2nd cannon)?

[oyunbagimlisi]

Hello. The vanilla battle tank has a single cannon weapon. While I use cannon shells because of their piercing feature when shooting nests and worms; I hit the dense large enemies around me with the explosive cannon shell.

But since there is only one cannon, changing ammunition is quite troublesome.

I don't want to add another tank.

What are the simplest codes so that I can add only a 2nd cannon to the vanilla tank? I think it will be a simple line. Can you help me?
