I should probably add, that in the case of bombers and strikers, they have a single trigger zone attached to them (moving trigger). Enter this and it randomly chooses a flag value, each having a time pass. When the Flag value is met and time has passed, the given groups Advanced waypoint has a switch waypoint added (in my case, their DP (Last waypoint, a landing waypoint), which condition is a given flag true.
This goes for the fighters too, which also has a hostile trigger zone. Same concept, enter this zone and it randomly chooses a flag value, one of which triggers a flag, which the groups advanced waypoint ROE etc condition has a given flag true.
Quite simple really, just crazy trigger intensive setup, especially since I have multiple client planes.
