Often abbreviated as AP. Action points are renewed each turn and are used to determine a unit's movement, combat, and other activities during a turn. Action Points are renewed each turn. The extent to which they are renewed can be affected by factors such as a unit's readiness. Action Points are also for other game activites, such as tracing supply and production, determining a plane's interception behavior. See the manual for details.
[Here would be a good place to list where variables that address how the number APs recovered each turn can be modified in the editor]
