We can model the idiotic civ12 bomber blocking ability by generalising the 
"layer superiority" rule to demand that a unit has to be able to attack 
all units in its own and any other listed layers.

I don't know how we can reasonably model the even more idiotic rule that
an attacking Fihgter might be forced to attack a Mech Inf rather than the

I disagree.  AI already has to deal with exceptions like F_IGWALL,
F_PIKEMEN, F_AEGIS and F_FIGHTER.  Raimar's proposal allows, by setting 
bomber own layer attack power to be 0, to do away with F_FIGHTER.  Split 
defence powers will allow to do the same with F_AEGIS.  But what about the 

I think it is the best to keep one system, therefore even splitting attack 
powers is not needed.

Note, that the pure layers redux proposal allowed full Civ12 compatibility 
(including all idiotic features like bombers falling out of sky when the 
Mech Inf under it is killed).  All you had to do is to put everything into 
one layer.

So my vote is for Per's original plan without additions.  Unless someone 
tells me how to implement F_PIKEMEN (well here you can just put all horses 
into a special layer ;) and F_IGWALL rules in the layered attack/defence
