Seeing as PB2 is unlikely to receive any more major updates, I'll post this here instead.
Basically what it sounds like: unique weak points for various vehicles. I have some ideas for weak spots for various vehicles if they are to be included in PB2.5.
The "/" indicates and/or.
Mobile r081-CS: The glass canopy/The wheels/The rear.
Hound Walker CS: The legs/The top.
Drone:
The black part in the back, since it looks pretty lightly armored/That tiny slit in the front.
Corvette:
The parts that are not covered by white plating.
