Gun depression is not modeled afaik.
Don't worry K-T, the first thing I did last night after getting it in the mail (well, install, of course) was run a bunch of AFV v. AFV tests for grins and to look at all the models. At 500m, 1000m, 1500m, 2000m, and 3000m, the Panther toasted T-34's of any sort with great regularity.
