Generally speaking we have to be very careful about dedicating time to "outlier" possibilities. There are a million things that probably happened here and there over the course of such a huge campaign as that of the Western Front (Eastern Front goes well beyond huge. My best example of this is one I've been using since the CMBO days... what I call the MG42 Bovine Meat Sponge situation. In brief...
A platoon of US infantry was pinned down by a single MG42. Everytime they tried to flank it the thing blazed away on them. Well, some enterprising soldier found a barn with a bunch of cows in it. They herded them into the kill zone and ran behind them to get into a dead zone which, in turn, let them flank the MG position. The MG42 killed the cows, the American infantry men killed the MG42 crew.
Points to consider:
1. This is a historically documented event which is entirely plausible.
2. It had a tactically significant impact on that battle.
3. It would probably be practical to do it within the space of a typical CM battle.
4. There is no code for cows, nor any code for using them as a wall of hamburger helper.
The question is, should we support such a thing because it happened? I think 99.9999% of you guys would say "no". Intuitively we all know that this maybe happened one or two times out of a couple million or so tactical engagements at this level. Any time spent supporting such a massive outlier would be a gross misallocation of development resources. Right? Right.
However, it goes a step further. When we provide support for a particular tactic, even if unintentionally, it will get used if a player perceives it to be beneficial (perception is more important than actual results in our experience). The use of that tactic can then be far, far out of proportion to how it was used in real life. This then leads to a fundamental problem with supporting outlier type situations:
The outlier situation is supported to make the game more realistic, but if it is used unrealistically often then that lowers the overall realism of the tactical environment.
Or put another way, if the Bovine Meat Sponge thing worked, then every time cows were found in a scenario the player would likely try to find a way of using them ("friendly cows") or killing them to denny the other player use of them ("enemy cows"). This in turn leads at least a portion of the battle to be twisted into focusing on something which is completely wrong to focus on from a historical perspective.
