For my part, anything that can follow these principles is welcome:
No combat unit destroyed by a weak non-warship transport unit, Naval combat is done according to usual A&A system rule:No auto-die, a roll is needed to destroy any unit, no exception at all
and no combat unit able to destroy more than 1 unit in the same combat round (AAA still an exception).
In addition, a roll is needed to provide escape for the weak, no predictable result.
