Maneuvering Attack

When you hit a creature with a weapon attack,
you can expend one superiority die to maneuver
one of your comrades into a more advantageous
position.
You add the superiority die to the attack's
damage roll, and you choose a friendly creature
who can see or hear you. That creature can use
its reaction to move up to half its speed without
provoking opportunity attacks from the target
of your attack.
