Armor refers to various types of covering worn to protect the wearer from harm. In the Age of Empires series, armor is a vital statistical value for units and buildings.

In Age of Empires and Age of Empires II, attacks are applied against armor of the corresponding type.

In Age of Empires, attacks other than melee/pierce usually have a non-positive value, meaning the attacker deals bonus damage against units (or buildings) whose corresponding armor has a lower negative value. If the target's corresponding armor is 0 (the generic base armor), the attacker will deal no bonus damage.

In Age of Empires II, attacks usually have a non-negative value. If the target is in the corresponding armor class, the corresponding armor is usually 0 (exceptions include the Cataphract and Condottiero), so the bonus damage will fully apply. If an armor value is not equal to 0, the damage is reduced by this value. Units almost always have non-negative armor, the only exceptions being Houses*, rams, Siege Towers, Elephant Archers, and Ballista Elephants. If the target is not in the corresponding armor class, the armor is 1,000 (the generic base armor), thus the corresponding attack will do no damage.

All units have two basic types of armor: melee armor (simply called 'armor') and pierce armor, which protects against most ranged attacks such as arrows. However, some units like the Throwing Axeman and the Mameluke in Age of Empires II deal melee damage (i.e. reduced by melee armor) at range. Depending on the unit type, the units may have additional armor classes.

Age of Empires[]

Damage formula[]

In Age of Empires, the damage formula against units is:

  • m denotes melee attack / armor.
  • p denotes pierce attack / armor.
  • If the attacker has a bonus AttackBonusi against the armor class i, then the bonus (minus BonusResisti) is added to the total damage. Usually, and . The attacker is said to deal bonus damage against the target when and .
  • kelev is the elevation multiplier (applied to both cliffs and hills), equal to 2/3 if a melee unit attacks below its target, 3/2 if a ranged unit attacks above its target, and 1 otherwise.

The damage formula against buildings is:

Units dealing melee damage[]

The following units deal melee damage and are affected by their target's armor:

Technologies[]

To improve armor for infantry, cavalry, and archer units, technologies from the Storage Pit must be researched.

Siege weapons, ships, and buildings have 0 melee armor and it cannot be increased by technologies or bonuses.

Age of Empires II[]

Damage formula[]

In Age of Empires II, the damage formula is:

Cavalier infobox (fully upgraded)

  • m denotes melee attack / armor.
    • If the attacker is a Leitis and the target is a unit, .
  • p denotes pierce attack / armor.
  • If the attacker has a bonus AttackBonusi against the armor class i, then the bonus (minus BonusResisti) is added to the total damage. Usually, . When , the target is said to have the armor class i (in those cases BonusResisti is usually less than 100).
    • kSicilian is the Sicilian bonus reduction multiplier, equal to 1/2 if the target is a Sicilian infantry, cavalry, or archer unit, and 1 otherwise.
  • kelev is the elevation multiplier. It is 5/4 if a unit attacks above its target (hills and cliffs), 3/4 if a unit attacks below its target (hills only), and 1 otherwise.
    • For Tatars, this value is changed to 3/2 when a unit attacks above its target (hills and cliffs).
  • kcracked is equal to 6/5 if the target is a building on a desert cracked terrain, and 1 otherwise.

Units dealing melee damage[]

The following units deal melee damage and are affected by their target's melee armor:

*The Fire Galley line also deals pierce damage.

The Bombard Tower used to deal melee damage before patch 1.0b.

While Chu Ko Nu, Kipchaks, and Scorpions main damage is pierce, they also deal 0 melee damage per projectile, meaning each projectile will do more than 1 damage to units with very high pierce armor but negative melee armor such as Rams and Siege Towers. In particular, Chu Ko Nu and Kipchaks are a good counter against rams since they fire multiple arrows, each of them doing 0-(-3)=3 damage.

Units with high melee armor[]

The following units have high melee armor and excel at battle against units dealing melee damage (values for fully upgraded units):
Infantry

Archers

Cavalry

Siege units
