Armies may Battle in Regions with Towers, which have a Natural Strength of 3 (counts toward your army's Natural Strength for purposes of Battle and determining Damage).
Towers are also considered adjacent to the Capital City’s Courtyard, so a defending player may use the Conscripts Tactic to move Units from their Courtyard into the Battle.
If the defending player loses the Battle, the Tower MUST take damage first before all other Units or Vessels in the army.
Towers are then “destroyed” and returned to the supply. A destroyed Tower may be built again on a future Build Action.
