I don't think many people here are trying to "stick it to wheraboos" but if folks are going to argue the KT/JT/ST aren't overrepresented then id say you are fighting reality not being identified as a wheraboo. Thier representation is indeed fiction.
The sturmtiger is a failure in combat history, There isn't any record of it forcing battalions into retreat. No record of it wiping out entire platoons, striking fear into American/allied troops hearts. that's a pretty big fiction compared to its gameplay role where it does these things.
I think what some people here are trying to point out regardless of some axis and allies contest is that these fictions have occurred many times prior. This one is somehow earth shattering.
I do think its a pretty niche crowd who cant concede the idea that COH has taken these liberties in fiction before and perhaps it makes this discussion interesting on another level. I can see how the folks in that camp would have trouble with authenticity if they thought the game had been fairly factual and faithful to history up to this point, which would be concerning.
The ST was not designed for "forcing battalion into retreat" it was designed fire support vs enemy strong position or in urban terrain.
As you can see in wikipedia though there at least one record of "wiping entire platoons":
"During this action, one of the Sturmtigers in Sturmmörserkompanie 1001 near Düren and Euskirchen allegedly hit a group of stationary Sherman tanks in a village with a 380mm round, resulting in nearly all the Shermans being put out of action, and their crews killed or wounded. This is the only tank-on-tank combat a Sturmtiger is ever recorded engaging in."
