In my opinion, Abstraction is a poor excuse here because of the lack of information displayed to the user. This is confounded by the game modelling tree trunks concretely and foliage abstractly. My frustration is informational, "Why can't my tank make this spot". Some options could be 1) An LOS mapping tool, 2) A Display mode for "walls" of foliage if it were caused by foliage abstraction. Also, I showed that the LOS/LOF target could reach the StuG and furthermore my tank had a contact marker at that location. I'd be fine if the game said that while I can draw LOS/LOF here, foliage was heavily degrading spotting on the target line. Similarly, the game could say what my tank crew was prioritizing in terms of spotting. I want to comment on the "possibility of such failure" as well. This is misleading excuse because the goal post here is to prove that the real possibility of occurrence is similar to that of the game. It is not to say that because one can happen in either, then it is fine. The relative chances of occurrence is critical though likely unknowable for the real case.

Is not excuse, is fact. They not little people fighting inside your PC they are digital abstractions. Agree the UI does show this failure poorly but all wargames suffer from much player information. Spotting failures could be too often but that is different from broken.

The poor tank crew didn't even know the stug was there! They had no prior information that the stug was even there, also this abstraction spotting and stuff in all in the manual.
