Soviet OBB T-62 designations

[Smersh]

I can understand how having 2 T-62Ms can be confusing but this is done with the T-55s. Ex. In the East German OBB there are 3 different T-55As.

But the current T-62M (unit 18) if it were called a T-62A, the more common designation. Will make it more clear, so people don't confuse it with the true T-62M which adds a laser rangefinder. Instead of the T-62A which adds a 12.7-mm DShK antiaircraft maching gun.

The other point is that currently the T-62 uses a completely different designation scheme then then the T-54/55/64/72.

Anyone with more information on T-62 variants?
