Stable

The Stable is a class of building that allows for production and upgrading of mounted units. It is typically unlocked after Basic Military Development has been researched, with unit upgrades available after Advanced Military Development. Cavalry are fast and tend to have high pierce armor, making them an excellent counter for archers. They are superb raiders but are expensive and are vulnerable to infantry, especially spearmen. The Stable is available to all civilizations except for the Aztecs.
