Wow! That is a detail level to which I strive in vain...
I already have one T-80U handy, in Russian tan-green camo (is it termed K-5 or do you mean something else?). It is merely extrapolated from existing icons, so not much to be praised for, but always better than a T-80BV icon.
Isn't there already a noteworthy T-55AM2 in the game? Look icon #1446 for a T-55AM2PBK, and icon #2667 for a T-55AM.
If you aren't satisfied with this, i know Joe Rieger did a T-55AM2 (or at least a T-55 with add-on armor and LRF) in his series of new T-55 icons, which you can find
here on the SPMBT Yahoo site.
I remember seeing a T-62 with 'Brejnev' eyebrows armor somewhere, but I can't remember where.
T-64U can be worth a try, but is it in service? Maybe Ukraine has upgraded its old stocks?
And doesn't the Merkava Mk3 Baz icon match the 2-D right enough? I know the armor layout must be somewhat different and the body should be quite shorter, but all Merkava icons seem to share the same chassis
