To incerase my fictional nation's power, i've decided to add more MBT into my arsenal, and upgrading the old ones

I've decided to close the Mouriner Series with S25B as the final series, but upgrades on further ver on this one is still possible with mounts of better optics and system, uploaded soon

And the new Main Battle Tank is also coming up, this one is using the European doctrine instead of soviet ones, meaning it was larger by size, it was under the name Zurion E1
