So far that I know of?
The only AI Unit ever put out there was the Type 14 U-Boot.
It was done as a test Unit that showed the path that no one seems to ever have followed.
The main problem seems to be that everyone expects things to work as they did in past versions.
If one is locked into that frame of mind?
You fail before you ever start.
I know from the Dev's themselves that they fell to that trap.
I might still have a version of the Type 14 that takes damages from Shells and Torps.
I also did a few tests that showed me the way to get damages to show.
But I'm not interested enuff to really follow up on it all right now.
