A stable is where mounted units are trained and healed. Cavalry units come in different sorts: light melee, heavy melee, light ranged and medium ranged.
Factions with access to Imperial Mandate have the option of upgrading their stables to Constabularies. These are sturdier, have a better line of sight as well as the ability to function as static point defences. Factions capable of constructing constabularies include: China; Mongolia and Armenia.
- Light cavalry: light horse  => light cavalry  => Trooper 
- Heavy cavalry: lancer  => knight  => noble knight 
- Skirmishers: mounted javelineers [1-2] => crossbow cav 
- Mounted archers: Horse archer (1) => mounted ranger (2) => Palace Gamekeeper (3)
A Constabulary has enhanced attack and defensive stats, making it as powerful as a Dark Age Tower.
