Damage model at very very close range

[stupor-mundi]

Generally you can reliably blow up a tiger from a t34 if you hit it in the gap above the tracks, below the main side armor, with APCR, if the distance is fairly small and the angle is near perpendicular.

It's happened to me a few times that this doesn't seem to hold true at VERY close distance. The first time it happened was a situation where the tiger had been damaged somehow and the turret traverse seemed even slower than normal, so I was able to avoid the gun by wheelying around the tiger for a while, sinking 25 APHE and 25 APCR into it, with no effect. Back then I thought the cause would have to be some other bug, such as that the tiger somehow spawned as unkillable. But since, similar failures have occurred a number of times. Right now I can think of 4 possible explanations.

* being too close means the gun's slightly higher position causes the angle to be off perpendicular too much, in the vertical

* the t34 sight is vertically offset from the gun? (don't think it is)

* there is some fuse activation logic which is applied to all ammo, even though for kinetic rounds it shouldn't

* something about the collision model that fails is the distance is too small
