Soviet OBB T-62 designations

[DRG]

Agreed this is nice info and strays off the topic a bit with the T-80 info but one thing a lot of lists like this we have seen lack is introduction dates for the new models and upgrades. It's great to get the details ( and it is ) but much of the information we see lacks the critical in ( and out of ) service dates which is critcal information

What I would like to see is a list like that for all models ( T-54 all the way to t-90) with the service dates included.

If anyone has real hard data on all the models WITH the in service ( and out of service dates if possible ) which can be matched to the detailed information on what changed in the new model/upgrade we would all go a long way to putting this issue to bed finally.
