Summary- If an enemy gun toasts one of your tanks but your other tanks don't fire back, it simply means they haven't spotted it yet. Meanwhile don't sit around waiting for it's icon to appear, just plaster the whole edge of the woods with area-fire by tanks and infantry to at least suppress it!
Also, at the start of your turns, click a blank area of the map to de-select all your units and get a clean slate overview of the situation, then begin selecting each of your units one by one to see what they can see through their eyes..:)
