Alright what does the opposed mean then?
Sorry, you have misunderstood what I meant.
The "opposed" means, as I suspect you correctly interpreted, that the leadership skill of the knight is
opposed to the leadership skill of the Marshal in determining who will control the knight's unit in combat.
However,
that never happens. There is no such code in the game, and never was. Those lines should be removed from the Wiki, as they are incorrect and misleading.
