Iron Horse Armor is a special type of equipment used to protect horses from damage. Crafted from iron ingots or found within chests in dungeons, strongholds, villages, or nether fortresses, it significantly reduces the amount of harm horses receive from attacks or environmental hazards. Unlike player armor, it does not degrade over time with use. This item is equipped by right-clicking on a tamed horse and accessing its inventory, where the armor slot is located.
