In fact this is the worst feeling.
I have had many experiences when say a Sherman V dropped smoke and hid behind it just 200 meters from the Tiger.
Then, instead of waiting for the smoke to clear, the Tiger coolly turns its back to the obvious location of Sherman V and focuses on some ridiculous infantry (not Bazookas or PIAT teams - these are at least understandable - it goes after some depleted infantry squad which has routed and can not pose an immediate threat).
So the smoke clears and we have the Tiger turn into a Sitting Duck with its back to the Sherman V. (And me sitting here clenching my teeth and cursing the Tiger.)
Of course the obvious question will be "Why do you allow the enemy tanks to close in at such a low distance?". But in hedgehog areas or even cities (e.g. the battle of Villers-Bocage) that's the farthest visibility on many occasions. And in any case that's not the point of discussion.
I have also seen that on some occasions the enemy tanks just turn into nationality symbols without any smoke etc. And then when my tanks focus on some other target, mysterious fire comes from the nationality symbols and knocks out my tanks.
Does this happen with all of you?
Are the designers aware of these issues?
Can these be fixed?
