A garrison will participate in any battle that occurs inside the zone of control of their settlement, even if the battle is not an attack upon the settlement.

Garrisons cannot leave the settlement they protect, and so are only useful defensively.

Garrisons are often not led by a lord, though a highly upgraded garrison may have heroes to lead it.

Garrisons must be fought and defeated to take a settlement.

Fortress Gates are a special kind of settlement with a large garrison.

Some landmarks also increase the garrison.

Garrisons are increased by upgrading the main settlement chain buildings, and by constructing defense buildings (eg: Basic Walls, City Watch).

Garrison armies are a special army automatically generated by a settlement to defend itself.

Please see the article on stances for more information.

Stances can differ for each race, and depending on the situation.

Armies can enter different stances which have different effects such as immunity to attrition or increased movement range.

When an army enters a settlement, it is said to garrison the settlement.

Units can also be disbanded altogether or re-named to something else.

Units which have lost troops can be combined with each other to create a single stronger unit, however the unit's rank will drop to the lower rank of the two original units.

Army losses can be replenished through replenishment.

Units take damage and lose troops (entities) through attrition and battle.

Armies can suffer attrition due to high levels of corruption or an inhospitable climate or rough terrain.

Units are recruited to armies/Lords, whereas Lords are recruited from settlements.

Armies can also contain heroes who can join/leave armies as they please.

Each race has a different style of flag for their armies on the campaign map.

If the Lord is killed/wounded in battle, then a new Lord must be recruited as soon as the battle ends.

On the campaign map, each army must have a Lord at all times.

Each army is moved together as a group with its Lord.
