Russian soldiers in late WW2 were typically very well equipped, as were most soldiers by that stage in the war (even German soldiers were pretty decently equipped late war, though mostly due to having almost no soldiers left to equip).
Late summer 1941 and even at points during Stalingrad, sure there were definitely times when soviet soldiers were being thrown into battle massively underequipped, but this was the exception rather than the rule.
By 1944 (even by 1943) the Red Army was more mechanised than the Wehrmacht and was better at Blitzkrieg than the Wehr ever were.
