Yes. US had pershing heavy tank but to late to make a difference at the end of the war.
Of course, heavy Tank must be a tech. Germany and USSR only.
Italy and Japan didn’t have the industrial capacity, the technology and money to produce medium and heavy tank. In 1941, japanese didn’t have any tank division!
Only tankette.
Light tank cost = 4 2,2,2 but attack at 3 in the first round of combat.
there’s a difference between a mechanized infantry. Light tank is stronger.

Heavy tank = (USSR 6) Ger 7.
