With the help of ATR (or maybe with guns, but it’s harder to do, without fatal damage to the tank), you can “chip off” the armor of the tracks, tracks, some decor (like cans) and other anti-cumulative armor.

The most interesting thing is the destructibility of anti-cumulative screens on the turret.
(Again, its hard to not destroy)
These details get lost after 2-3 shots of the PTRS (there is no good analogue of the PTRS) with a characteristic sound, most often they appear for a while in a broken form, and after a couple of minutes they disappear, sometimes they remain in place at all, although without a collision, or vice versa, they do not exist, but there is a collision. (all cases can be seen in the screenshots, for example, the remaining on-board armor of the tiger simply did not disappear)
Btw, all the destroyed parts are missing on the carcass of the destroyed tank in any case.
