The Gondor Tower Guards are the elite infantry of Gondor. They are Minas Tirith's permanent garrison and defend it against all attacks. They are equipped with thick armor and broad shields to protect them and a long spear to attack; granting them their upgrades turns them into practically invincible tanks. They are also known as Citadel Guards, and they are available in the Gondor Barracks from which they emerge in groups of 10 units.
