1. It is a museum piece painted in standard modern Russian cammo. Not sure if this is legit.

More pictures can be found in this primeportal folder...like 15 pages. I looked into it a little more and while I can still not find any numbers on how many T-80B were modified this way, essentially what George and I were talkingabout seems to be the truth: T-64B and T-80B were found to be vulnerable to the "new" 105mm gun/ammo systems, especially after some Isreali ammo was tested in the Soviet Union, and so they welded 2 30mm sheets, for a total of 60mm, to the front glacis of both tanks to beef them up. This was more of a concern with the T-64 series than the T-80B for some reason, as there are far more T-64's converted (or at least photographed) than T-80B's. Not too long after, ERA bricks became available, so not upgraded tanks were simply equiped with ERA instead of the added front glacis armor. New T-80B had built in improved glacis armor, IIRC, but I need to look into that to be sure (this would be the improvement of the hull that would lead to the T-80U type hull).
and yes, the T-64B with the added glacis armor were fitted with ERA as well.
Notice the cutout in front of the driers hatch and around the glacis mounting lug strips.
