Soviet OBB T-62 designations

[Smersh]

no, your right.

I have been playing around with my OBB the past week. I must have had a different unit name, then I changed it back to it orginal.

edit: I've been looking at Russian sources, they repeat exactly what Djiuce posted on the first page. It does say the AAMG began being installed on some tanks starting in 1969. Currently unit 18 "T-62M" with the aamg, is available starting in 1971. Thats probably when it was seen publically or NATO identified it.
