Mentality and Arrows are imo 'More' (or 'Less') settings - More Defensive, More Attacking. Its not a "Defend as if your lives depend on it" or "Venture forward and you will be shot". Orders in general are preferences not restrictions.......imo.

Ofc the preferred style in Manager tab has nothing to do with this 'research' (it doesn't have anything to do with Mentality Orders either ).
