Therefore, for example, armoured management of 4th guards tank army in April, 1944 persistently asked the higher organisations to find at least 20 SU-122 as SU-85 were unsuitable for struggle against the strengthened machine-gun points.

I suggest to clean this gun # 030 - 122mm M30 L22 from game and SU-122 before occurrence SU-122-54.
