+;------------------------------------------------------------------------------------------------------------------------------
+; Arulco Special Division
+;
+; Control over a number of new features will gradually be given over to a second strategic 'AI' - the 'Arulco Special Division'.
+; This should control if, how and when these new features are used by the AI.
+; 
+; It has its own 'budget', which allows it to purchase new actions. This serves to limit the amount of the AIs actions.
+; It also gives the player a way to compete with the AI - lower the AI budget, and the AI can do less harm.
+; For example, part of the AI budget might come from mine income, which the player can take away.
+; 
+; If possible, the AI should have to buy and maintain its assets. 
+; This way the player could harm the AI by specifically targetting those assets if he chooses so.
+; Ideally this gives the player another immersive way to do sth. in the game.
+; For example, enemy helicopters have to be bought, fuelled and repaired.
+; In order to stop enemy heli raids, the player could 
+;   - shoot them down
+;   - steal enemy fuel deliveries
+;   - sabotage enemy helis in their airfield
+; 
+; There is a cyclic update of this AI. Each time the AI decides whether it wants (and can afford) new assets.
+; These assets then have to be ordered and can only be used once arrived.
+; The AI also decides how to use these assets.
+; 
+; This feature is not recommended for new players.

+; This feature allows the AI to use helicopters to rapidly deploy troops, similar to Skyrider.
+;******************************************************************************************************************************
+
+;------------------------------------------------------------------------------------------------------------------------------
+; Once the AI is aware of the player using Skyrider's helicopter (indicated by a cutscene), it can purchase some for itself.
+; Just like the player, it can then fly a small squad around on the map and deploy them.
+; Helicopters have to be fuelled and repaired, which consumes AI resources.
+; 
+; The player can shoot down helis via SAM batteries, and infantry-based MANPADS. Due to engine limitations, this cannot be 
+; done manually.
+; If a helicopter was downed, there is a chance that the pilot survived and can be killed or captured by the player 
+; (downed pilots are counted as officers with regards to Prisoner Interrogation).
+;
+; Provided the sector has the correct tilesets, it is also possible to destroy enemy helicopters on the ground if they
+; are parking in their home base.
+;
+; Enemy helicopter raids target strategically important targets to the player (towns, mines, inactive SAMs, roads, farms if
+; MILITIA_VOLUNTEER_POOL is on) that are lightly defended and reachable without too much hostile SAM exposure.
+; 
+; The AI can have up to 2 helicopters, each carrying up to 6 elites. Travel time per sector is 10 minutes.

+; Settings related to SAMs
+; These settings only affect enemy helicopters and attacks against them. For Skyrider, see Helicopter_Settings.ini instead.
+;
+; Every time an enemy helicopter moves and is known to the player, his air defense will try to shoot the heli down.
+; There are two kinds of anti-air-defense:
+; - SAM sites cover a large amount of the map and can fire in any of 'their' sectors (see SamSites.xml).
+;   They require control of the sector. They can be rendered inactive by damaging their control computer.
+;   Damaged SAM sites can be repaired by the player in the strategic map.
+;   They uncover any enemy heli in their sectors, but will only fire if staff (militia or mercs) is present.
+;   CTH depends on quality of the staff and range to the target.
+; - MAn-Portable-Air-Defense-Systems are infantry based missile launchers. They can only be used by mercs.
+;   They can only be used on targets in the same or adjacent sectors.
+;	CTH depends on weapon status, range and the user's cth with launchers.
+;	The launchers have to be armed in the inventory, it is not required to have them in the hands.
+;
+; For balance reasons (there should to be an incentive to use MANPADS over SAMs), derault MANPADS damage is a lot higher than 
+; SAM damage.
+;------------------------------------------------------------------------------------------------------------------------------
+; the AI does not consider attacking a sector if the flight path (to and back) contains more than this number of sectors
