Ah Moltke, aka "The Pillbox that Wouldn't Die", aka "Case Study on how Luck Can Turn a Battle".
Leading with the armor was a necessity in that one, due to the placement of the aforementioned pillbox. Once its gone, things are relatively simple for the Soviets: Lay smoke, surpress with the armor, cross the bridge, let the SMGers do their thing.
Of course, if that pillbox refuses to go down, you have to get... creative (see AAR).
