It occured to me that the Begleitpanzer 57 has a small mistake regarding its hitbox. A small one, yes, but it undoubtedly cost me a battle now, as my dart went right through without any hit whatsoever - as if there was a gap.
I went to protection analysis to recreate the shot I made. You can see down below that I cannot even simulate a shot, as there is (apparently) nothing to hit, Note the grey cross. This is beyond me, as there obviously IS something, even if for the small plate on the back, but there is also a bit of the cannon breach, specifically the feed, as shown on the x-ray.
This plate is a part of the breach, by the way. 150mm of structural steel.
While the blank area is small and one would not usually aim for it, a hit to this specific area should be a crippling one, a destroyed breach at the very least, ammo explosion possibly as well.
