Civ4UnitInfos

The Civ4UnitInfos XML file controls data related to individual units: for example, a unit's strength value or hammer cost. There are also more detailed options, affecting things like transport capability, prerequisites, and other complex features.

All tags must be opened and closed; the first is the 'open', the second the 'closed' tag. If nothing goes inside a 'list tag', then it should just be the opening tag with a / before the closing bracket. The following tables contain all available tags, as well as their purpose and accepted values.
