Unit

A unit is something that can be built in one of your cities and can move over tiles. A unit can be both military or peaceful. Generally speaking, there are land-, air-, and sea-based units.

Generally each unit can move and/or attack on each turn. Each type of unit has a basic number of movement points per turn, which may be used up in the first step or attack. Terrains, terrain features, and improvements affect the number of movement points used.

Land units must move only onto land tiles (or ships), sea units only onto sea tiles (or cities). Air units may use any tiles, and if allowed to pause at the end of one turn outside a city or carrier or airbase, they may be over water.

There are currently 1,040 units, divided into 52 categories.
