Huskarl (Age of Empires II)

Game info
The Huskarl is a unique Gothic infantry unit that has a good attack and reasonable speed, but their biggest asset is the base 4 pierce armour, allowing them to shrug off most ranged attacks and are thus a great anti-archer unit. An army of these can destroy a Castle with minimal effort, since the main attack of the castle is a volley of arrows.
