Not sure what you mean but here's my early answer.
Each Unit, sea or air, has a zon file.
That's the determing file for damages for that unit.
Those zones are connected to the zones.cfg file.
(In SH4 there may be other factors I'm not up on!)
I am not aware of any tool to read the zones on SH4 files
in a visual way.
Yet.
I can read them in a visual way after some Hex work.
But seeing as no one likes doing Hex work?
Wait for a tool.
Hint,
Anvert is very close.
He is just missing a few insights.
