Looking at ref material for my next big project and found this page, If you need to know
everything about the T-62, T-72, T-80, BMP-2 ,BMP-3 and a few other types this page goes into great detail
on how they evolved. Fantastic photo's and write ups on almost every aspect.
Well worth a look and it appears more types are coming. I just had to share this link
