Info on aeronautics page is extremly old,for example info about 280mm front turret thickness came from old Janes magazine, and is extremly unaccurate.LOS thickness of T-72 tank is 320mm at the gun area and around 430mm at the corners. 80mm front hull info is wrong, as older models had combo 80+105+20 (steel,alumina,steel),newer models (T-72A) had 60+105+50 composition.T-72B has better composition as it has additional armor plate (30mm SHS, or HHS) Whole nomenclature problem with T-72 tanks is Janes fault as they (and West) had limited info about this tank, they even spoke about a T-74 tank (never existed),Janes T-72A,B,G,M export tank nomenclature is wrong. T-72A and T-72B were just plain T-72 tanks with steel turrets (without inserts in turret cavities)they had nothing to do with russian T-72A and T-72B FST-1.
T-72G was simplified version (cheaper) of T-72M export tank

T-72M wasnt a Warshaw pact version of T-72A.For exampe Czechoslovakia got first T-72 in 1977-78.They were just simple first russian model T-72 tanks.T-72M was modernisation of these tanks. They added LRF,better firecontrol system and improved stabilisation (in comparation with base T-72 model from 1973) T-72M1 was a new build tank. Its armor protection was same (at least)as in russian T-72A,front hull got 16mm SHS plate + another FC and stabilisation upgrade.First T-72M1 tanks were avaiable in 1985-86, year when russian had new T-72B and T-80U tanks, so they allowed Warshaw pact countries to build their version of T-72A tank (they did same thing with T-72 base model in 1978)
There were no T-72BV or T-72B1V tank ever. T-72B1 and T-72B tanks had ERA from begining (some tanks were stripped), same thing happend with T-80U, there were no T-80UV version...
Whole info at this page is old,(1996-97), i have old armor page downloaded in my computer.

I apologise if my post is too aggresive, but my english is not my strongpoint...
