I understand why the attention of infantry faced with other infantry, or worse, an AFV, in their location (or even in bypass) is all on those opponents. But what is the rationale for why an armored behemoth, largely impregnable to infantry weaponry, especially early in the war, would not be able to fire out of the same location, but instead can only fire (assuming right facing) on those opponents? A bypassing AFV especially, being 15-20 meters or so from infantry holed up in woods or a building, would seem to have little inherent notice of or care about said infantry, and those infantry couldn't be blocking LOS or anything else it seems. What am I failing to consider? Or is the rationale largely in game terms, not simulation? That is, because VBM Freeze, already a high-powered tactic, would be dramatically unbalanced otherwise?
