This unit is very strong against Bowmen and Archers, as they can slice into second row in the very beginning; however, they are very fragile relatively to other units. Their lack of armor is hard to justify without looking into their speed. Cavalry easily the fastest unit in the world, and provides speed boost to the overall troop, which makes fast attacks against cities easy to do.
