I know and understand that some models have more than one to choose from. My point is that it says that to make a single strike multiple models choose a single attack. It does not say that to make a single strike multiple models EACH choose a single attack. The grammar in that sentence from the rules I quoted earlier does not make sense if it means what everyone seems to think it means.
It never, ever uses the word "each" in the section about disengaging. If you think I'm wrong, please quote it from the book.
