I have not looked at the scenario yet but it may be an experience issue with the US crews being somewhat on the low side and the SU-85 being somewhat on the high side

EDIT..... Just checked the US armor tends to be mid 60's experience and that SU-85 is 71 which is NOT a big difference but the German armour in general is mid-low 70's experience but even that is roughly 10% higher than the US armour and it's the US side that has to advance, shoot and move
