Somehow it was called M4.... But more commonly known as Sherman, was it? I got the only blueprint from Kourindou.

The best thing about the endless caterpillar track is that it was developed to be able to go both on and off-road. It's still a matter of course but the tank can't get wet from rain! As long as the iron balls don't get wet, we'll be fine! Maybe! To some extent!

This push button is even more amazing! Why do you think you are able to talk comfortably in such a closed room in this kind of machine?

That! Is! Because! It generates the negative ions and works as an air conditioner.
