Mounted combatant.

You are a dangerous enemy to face when mounted. When mounted and not incapacitated, you gain the following benefits:

You have advantage on melee attack rolls against any unmounted creature that is smaller than your mount.

You can force an attack that targets your mount to target you instead.

If your mount is subject to an effect that allows it to make a Dexterity saving throw to take only half damage, it takes no damage if the saving throw succeeds, and only half damage if it does.
