Lancerillager/Cavalryman

Illager gets a new member, namely Lancer or Cavalryman, or as I would prefer to call it "Cuirassier", They are Illager type, will appear in Raids, they ride horses, use Iron Armor, Using a spear as a weapon. They will charge using Spear to the villager or player, The stronger the charge, the stronger the damage. The counter method is fire. If we light fire around us to face the Cuirassiers, it is like the square formation during the Napoleonic Wars, because the horses will retreat and not dare to pass through the fire, the Cuirassiers will just circle around the fire while looking for a gap. When you kill them, they will drop a Spear, the armor they are wearing, and an emerald (I don't know, I don't have any idea what items they will drop).
