What happend if you try to shoot at a character that have joined an unit with an missmatching base. (like a cavalry into infantry)
Is it possible to target the character, even if the character it self is out of the LOS of the shooter ? But the unit that is has joined is into the shooter LoS ?
So in your example, if you hit the unit e.g. with a catapult, you can distribute the high-strength hit onto the character even if you can only draw line of sight to a single R&F model (by the way, matching/mismatching base doesn't matter in this situation; what's important is the height/type combination).
