How do air units work? What are the different “missions” they can do?
Air units work in a different way than land or naval units in Civ3, as well as the way they worked in Civ2. In Civ3, an air unit has to be ‘stationed’ in either a city or an aircraft carrier (or an airfield, which is a worker-made terrain improvement, in either Play the World or Conquests). From their base, they can conduct various missions, all which take up their movement for that turn. Before we go over the missions, here are the different stats used for air units: Operational Range (the range which the airplane can do a mission), Bombard Strength (literally the strength of their attack), Rate of Fire (the maximum number of Hit Points they can take off from a unit), as well as Defense Strength, in case an opposing air unit or land unit attacks them during their mission. In Conquests, air units also have the ability to be lethal – that is, they can kill the unit they are bombarding. In Vanilla and Play the World, air units cannot kill.
