Units are troops used for combat and expansion in Polytopia.

There are various types of units in Polytopia. The most basic unit is the Warrior. Other types of units include the Rider, with extra movement, and the Archer, with a ranged attack. Different types of units are unlocked by researching the appropriate technologies: for example, the Riding technology unlocks the Rider. Each type of unit has unique stats and skills. Also, each type of unit has an unique icon shown at the upper right of every unit on the map. For example, the icon for a Rider is shaped like the head of a horse. This feature is useful for units carried in naval vessels, as their icons tells the player what type of unit is inside the vessel. 

Vengir City

Only one more unit can be trained in this Vengir city until it is upgraded.

Units are typically obtained by training units in cities. The maximum number of units a city can support is equal to the number of population bars (shown below the city's name) it has. Dots in the population bars of a city represent the number of units supported by that city; if every population bar has a dot in it, no more units can be trained in that city until it is upgraded (which increases the number of population bars it has by one). If a unit captures a city or village, then it will be supported by that new city instead of the city it originally was supported by. You can see which city a certain unit belongs to by clicking on the unit, then on its icon in the bottom-left corner. This feature can be useful when you have to disband (or kill) one of your units from a specific city (typically a damaged one) in order to train a new unit in that city.

Each tribe starts with one unit in their capital on turn 0. Most tribes start with a Warrior; however, tribes with a starting technology that unlocks a different type of that unit will start with a unit of that type. For example, Oumaji starts with the Riding technology and a Rider. (The exception to this rule is ∑∫ỹriȱŋ, who stars with the Forest Magic technology allowing it to enchant animals into Polytaur units. Despite that, Elyrion still starts with a Warrior unit in its capital.)

The aesthetics of each unit change depending on which tribe it belongs to. Each tribe has a unique color and helmet. Also, the animals mounted units such as the Rider and the Knight ride vary from tribe to tribe. (These animals are the same animals that appear as resources on each tribe's terrain.) Finally, Battleships have tribe-specific decorations.

Veteran Promotions

Once most non-naval units have killed three enemy units (through attacks and/or retaliation), they can be promoted to a Veteran. Promoting a unit increases its maximum health by five and heals the unit completely (to the new, increased maximum health). Therefore, players may choose not to immediately promote a unit, instead saving the promotion to use it as a "heal."

Super units (e.g., the Giant), units with the carry skill (naval units), enchanted units (i.e., Polytaurs and Navalons), and units that cannot kill other units (i.e., Mind Benders and Ice Archers) cannot be promoted to a Veteran.

Upgrading Naval Units

Boats can be upgraded into Ships for 5 stars, and Ships can be upgraded into Battleships for 15 stars once Navigation is researched. (The total cost of upgrading a Boat into a Battleship is 20 stars.) Upgrading a naval unit does not heal it.

Battleship Warning

The warning that appears when attempting to move a Battleship onto land

Moving an upgraded naval unit onto land causes the unit to permanently lose its upgrade: if that unit is once again moved onto a Port, it will become a Boat.
