The general trash units in Age of Empires II, with their final evolutions

Trash units are military units that cost no gold or other rare resources. In all games of the Age of Empires series, there are several units that are considered "trash units". These units can be massed easily and often cost very little resources. For the most part, they are useful for defending a location early in the game or countering certain enemy units but can be taken out easily by counter units that cost gold. The term "trash" refers to the fact that most of these units only require the most common resources which are more easily disposed of than other resources (usually wood and food in all of the games).

When a player is using trash units they are usually trying to overwhelm their opponents with quantity instead of quality, or using them as cannon fodder to occupy the enemy troops to give the player time to create a more powerful army. Trash armies are also essential to long games without trade and on maps where gold is limited in quantity.

Age of Empires

Unlike the other games of the series, there are fewer varieties of trash units in Age of Empires, and two of them are even considered "elite" by the game (Scythe Chariot and Trireme). The complete list of trash units of Age of Empires:

• Clubman → Axeman
• Bowman
• Scout
• Chariot → Scythe Chariot
• Chariot Archer
• Scout Ship → War Galley → Trireme

Age of Empires II

In Age of Empires II, there are only three main lines of trash units: Skirmishers, who have attack bonus against archers, Halberdiers, who have attack bonus against cavalry, and light cavalry units, who are used as scouts early in the game, have attack bonus against Monks, and are effective against archers.

In The Forgotten, the first unique trash unit was introduced, the Magyar Huszar, that can turn into a trash unit after the Corvinian Army technology is researched. It is an improved version of the light cavalry units and equipped with an attack bonus against siege units. In The African Kingdoms, another unique trash unit was introduced, the Genitour. It is a shared unique unit, hence team bonus, of the Berbers. It is essentially a mounted Skirmisher and also has an attack bonus against archers. In Rise of the Rajas, the third unique trash unit was added, the Imperial Skirmisher, which is an upgrade of the Elite Skirmisher exclusive to the Vietnamese and their allies. Also in the same expansion, the Malay unique technology Forced Levy removes the gold cost from the Militia line units, turning them into trash units for them. Last but not least, in the Definitive Edition, Persians now have Kamandaran as their Castle Age unique technology, which changes the cost of the Archer line to only wood. Also in the Definitive Edition, Cuman Elite Kipchaks can partially be considered a "trash unit", as the Cuman Mercenaries technology enables them and their allies to train 10 Elite Kipchaks for free at the Castle.

The complete list of trash units in Age of Empires II:

• Spearman → Pikeman → Halberdier
• Archer → Crossbowman (Persians only, after researching Kamandaran in the Definitive Edition)
• Skirmisher → Elite Skirmisher → Imperial Skirmisher (the latter for the Vietnamese and their allies only)
• Scout Cavalry → Light Cavalry → Hussar
• Magyar Huszar → Elite Magyar Huszar (Magyars only, after researching Corvinian Army)
• Genitour → Elite Genitour (Berbers and their allies only)
• Militia → Man-at-Arms → Long Swordsman → Two-Handed Swordsman (Malay only, after researching Forced Levy)
• The ten free-to-train Elite Kipchaks enabled for Cumans and their allies after the Cuman player researches Cuman Mercenaries.

Exceptional trash unit civilizations

• Byzantines - The Skirmisher and Spearman lines are 25% cheaper, saving 15 food and wood per unit.
• Magyars - The Magyar Huszar with Corvinian Army researched is effectively a more powerful Hussar. Magyar Scout Cavalry line is 15% cheaper.
• Malay - The Militia line with Forced Levy is highly effective against most trash units, taking less damage from Skirmishers, crushing Pikemen and Halberdiers with similar resource costs, and trading evenly with Hussars. The Malay Fish Traps provide endless Food.
• Persians - Kamandaran turns Persian Crossbowmen into trash units, while remaining better than Elite Skirmishers at fighting melee units. This is in addition to Halberdiers and Hussars with all their respective useful upgrades.
• Spanish - Have Halberdiers, Elite Skirmishers, and Hussars, as well as all Blacksmith upgrades, which cost no Gold for the Spanish. Supremacy effectively turns Villagers into trash units.

Age of Mythology

The concept of trash units is completely foreign to Age of Mythology, as all human soldiers, and heroes cost gold, and all myth units cost some form of favor.

As it is possible to accumulate gold by trading with one's own Town Centers, gold is gathered much faster than Age of Empires II and spawns always near one's initial spawn-point.

The closest examples to traditional trash units in Age of Mythology are the Hypaspist, Khopesh Swordsman, Ulfsark, Slinger, and the Spearman.

Originally, trash Scout cavalry were intended to appear at one stage, costing 70 Food to train, however the feature was removed, and the Kataskopos and left over files are the only remnants of this.

Age of Empires III

Native units partially fill the role of trash units in Age of Empires III, as they are usually cheaper, but less powerful versions of normal units. Also, they don't contribute to the population limit.

Most European civilizations have the Crossbowman and the Pikeman, who can both only be upgraded to veteran status, but serve as cheap cannon fodder and early game rush units.

Many civilizations have their own unique trash units. Examples include the Russian Strelet, Aztec Macehualtin or the Indian Sowar and Zamburak.

The Chinese are completely built around the concept of trash units, as their soldiers are cheaper and weaker than those of other civilizations, and can only be trained en masse.
