Air Force Modifier

Biplane Squadron n/a +15% The Air Force Modifier is a bonus that will adjust the combat strength of one side if they have any air units in the region and the other does not. If they both have forces, they fight an air-to-air battle to eliminate one side. The highest possible modifier is applied regardless of numbers of units - if you had 500 Fighters and 1 Jet Bomber in a battle with 500 ships, the combat strength of all your ships would be modified by the Jet Bomber bonus but receive no bonus from your Fighters.
