This goes for the Sturmtiger as well
Yes, because ST has a turret which rotate in opposite direction which leads us to 180degree turn when reached the target.
Unless you are advancing with ST using reverse
I mean, really. Dont argue. Last time you tried my signature was born and today you thought that railway is more devastating than ST so...
Its cool that you are using stats and that you are not axis fanboy anymore, but sometimes you need to stop.
As for the avre, it should have lower damage than ST. Its just a mortar, not rocket.
