If you have the M1A1/2 then the natural opponent would be the T-55, T-62 and T-72

The Modern T-series of Russian made tanks are represented in many modern conflicts and while maybe not popular in the West, the rest of the world would love to model some variant that seems as wide open as the T-34 variants.

If Tamiya does modern T-XX variants, then the demand for M1A1/2 would rise substaintially.
