Now, on to other edits-

MTA-01 was offically the first to get ISR composite, but the AGMBT-01 was the first true widespread user of ISR composite, using it for the entirity of it's armor. Also one of the first tanks to mount a 170mm cannon. It was also the first, as far as I know, to use modular armor extensively on this wiki, and has become a standard for all of Yevata's tanks.

Also, the BY 20-10, I'm fairly certain was the first large style MBT on this wiki.

the MTA-01 is one of those odd 1/2 generation tanks. While at first it used standard steel armor and a variaring cannon, it eventually got composite armor and a better engine.

Many of those 2nd generation tanks ACTUALLY have ISR composite. C-1 Black Tiger Mk. III  C1H1 Viper MBT  BY 20-10. Mostly due to ISR's widespread trading of it(a bad move, in hindsight...). Though the Matilda will be the first(and currently, ONLY MBT, until I upload it's hover MBT varient) to use the improved Yevata Composite(should come up with a different name, really, but meh)(which is 200mm better when thickness of material is 100mm(ISR is 500:100)). And soon enough, the first one to use nanobot modular armor(basically, nanobots move the armor onto the tank, and even inside the tank, allowing the tank to be more heavily armored in specific areas).
