T-72M1 question

[brummbaer]

Being interested in this, in time I've collected what information I could gather about the T-72 seemingly-endless variants. Most of this come from a Tank_net thread of some time ago, and from this one as well (Marek you'll recognize much of this as yours ).
I hope it can be of some help, and in (very likely) case of some needed corrections/addenda please let me know.

I would like to ask a question about T-72s since there are so many knowledgeable people in this thread. Could someone identify this type for me?
