I do believe its an m4a3 105 or m4 105, and a number of countries that still use old tanks are around, a quick search says that 130 t-34 were still in service in 2018, i wouldn't be surprised if such a mass produced tank was still being use SOMEWHERE
I just don't think M4 Sherman tanks are in service anymore. They were being phased out in 1945 by Pershing.
