The Soviets did, indeed, have some awesome equipment near the end of the war...and in large numbers.
But the production of a lot of it was dependent upon supplies of critical materials from the West, as well as on no one bombing their mines, factories and logistical lines of communication. WRT the latter, the 8th Air Force and elements of the Pacific air forces would have done immense damage to the Soviets.
Their logistics also SUCKED. A modern army requires food and fuel - and part of Patton’s plans for the Soviets was to utterly destroy their fuel transportation system, stranding all of that great equipment in the field after the first engagement. We’d have been able to mop up a few million guys with small arms fairly easily in comparison.
I don’t think we could reach Soviet industry even from bases in Germany. Maybe B-29s could do it.
As for destroying Soviet logistics, it is important to remember that the enemy gets a vote. The Germans had been trying to this for the entire war and never succeeded.
