Warsaw Pact and TI

[PlasmaKrab]

Going out on a limb here, I'd say that some of the most recent Russian tanks (T-64B, T-72B, T-80, T-90) could be entitled a vision rating around 30. Same for some of the latest non-TI night sights like the German PZB-200 (see Leo1A1A2 etc.).

Back to topic now, has anyone any info about local (e.g. Czechoslovakian, Polish, Yugoslavian pre-'90 thermal sights variants? I think all of the non-Russian 90s upgrade use import thermals, but that's it AFAIK.

Now if you're going to clean the Russian OBF from all the undesired TIs, don't forget that a vision of 40 can also model GSRs, like that on the early BRMs. To my best knowledge the original BRM-1 (model 1976) already had a pop-up GSR with a quoted detection range of 12km.
Also, what about the BRM-2? I couldn't find any data about a dedicated recon version of the BMP-2, where does the idea come from?
