A side note based on my understanding...
T-72BV is not a proper designation. All T-72B were designed with ERA in mind (notice the repositioned smoke dischargers). The only instance of a T-72B not having ERA was during a parade in 1985, but those would have been fitted with ERA before being activated. T-72BM, as I understand, is another case like this. It is still a T-72B, just with Kontakt-5, making it the obr. 1989.
Sadly I know that it was not the proper designation, however with Kontakt-1 ERA, I believe it should have V (Vzryvnoi = explosive) in the name. Tanks in the CCCP as you may already know usually had Obr then year, to resemble any production + upgrades (exception of big model changes like T-72A then to the T-72B). If we look at the T-64BV we have ingame, Eugen has given us the T-64BV Obr 1988 with 9M128 Agona ATGM (Which was in service in 1988) rather than the Obr 1985 with Kobra (In reality there was better version of Kobra I believe at that time period which would of likely been 9M112M2.
But back to name changes, it was soon as I touched the Japanese vehicles, in particular renaming the Japanese tanks to Type 61, 74, 90 etc. Is when I got the errors upon starting the game. Also once I had changed the names of the vehicles, they were not shown in the NDF_Win file, where the units main statistics are (Class 81 I think it is or whatever its called).
