T-72B4?

Thanks to S300V4 for the link!

Wow.  A T-72B4?  I need a chart that details all the upgrades to this tank and how the Russians rank them as far as capabilities.  They have the T-90, various versions of the T-72 and now the Armata.  What tank is the most capable (leaving out the Armata).  If a unit has T-90's is it more highly regarded than one that uses T-72B4's?

I need to make nice with an intel bubba to help me sort this stuff.
