 * The factions should contain the aircraft classes for all Pretense mission types, otherwise the campaign experience might be sub-par.
     - Example: Pretense supply injections make heavy use of fixed wing transport aircraft, and specifically the An-26 to allow transports to land at smaller airfields too.
 
+Pretense has its own economy when it comes to frontline units, garrisons, buildings and so on. Purchasing frontline units in the Retribution campaign is therefore not necessary, because the Pretense script will control the purchasing of ground units once the campaign has been started in-game. Air defence sites will be placed at those control points / zones which have a site of the relevant type in the Retribution campaign. Example: if Maykop has an SA-11 site in the Retribution campaign, it will have one in the generated Pretense campaign correspondingly.

 # Missions and squadrons
 The Pretense generator will generate AI Pretense missions and also attempt to create the desired number of player flyable slots at each airfield.
 1. For the initial controlling faction at airfields durign the campaign start, the AI flights will be generated based on the campaign yaml and the campaign creation wizard when the Retribution campaign is generated.
