King has many isn't our slogan, with M1 destroyed one shot from T-72 or a couple of pogankas (RPGs) you have no chance.
I have told you, I studied a weapon engineer conventional warheads. D-81, a 125mm smoothbore cannon is something of an engineering marvel. You don't have a concept of engineering art. A gun sending an AP sabot at 1850 meters per second having recoil of 30 cm - when a 40 ton tank on asphalt moves a meter back with each shot.
You've done it by taking tanks as old as World war II era out of storage and trying to refurbish them. But you're running out of those now. You can't produce tanks as fast as you're losing them.
You've got maybe two or three years at this rate before you're fucked
