Garrison

Garrison refers to the act of placing units into structures.

In Age of Empires II
In Age of Empires II, the buildings that may garrison are:


 * Town Center: up to fifteen Villagers, Foot Archers and/or Infantry
 * Barracks*: Infantry
 * Dock*: Ships
 * Archery Range*: Archers
 * Stable*: Cavalry
 * Watch Tower/Guard Tower/Keep: up to five Infantry and Foot Archers
 * Castle*: up to twenty of
 * Siege Workshop*: Siege units
 * Monastery**: Monks and relics


 * Buildings may only garrison units if the rally point is set on the building. Units may eject, but after doing so they will be unable to reenter the building.


 * The Monastery may only garrison monks if the rally point is set on itself; monks may eject, but after doing so they will be unable to reenter the building. However, relics may be garrisoned and ejected at any time.

There are several advantages to garrisoning units. While garrisoned, units are immune to damage or conversion; if the structure is destroyed they emerge unscathed. Also, damaged units slowly regain hitpoints while spending their time inside a building; castles in particular have a faster hitpoint regeneration rate than other units. Researching Herbal Medicine increases the rate at which units regenerate while garrisoned. Also, garrisoned villagers and archers will increase the damage output of watch towers, guard towers, keeps, castles, and town centers: very useful considering the fact that the garrisoned units do not take damage whil dishing out plenty of their own. Cho Ko Nu in particular dramatically increase the damage output of the aforementioned buildings. Finally, if the enemy has Spies researched, garrisoning units inside buildings will keep opponents guessing as to the true makeup of a player's army.
