I think if you would have started a new thread you would have a better response because this thread is meant for the collection discussion
Then the information you provided definitely is not enough for scripters. You have to tell them exactly what you want the script to do step by step. And it should be one universal script for all missions (otherwise it would take to much time), thus success criteria must be the same.
E.g. you can place a group of vehicles at each target (maybe several groups - need testing). Then you place a trigger in FMB with big enough radius to include these groups. The type of trigger sounds like "vehicles in the area destroyed by 60%".
Then you place second trigger in each mission on an airfield where the player must land. The trigger type is "group pass through". (If he took off from the same airfield, it would be a bit complicated, as he would pass the area twice. You have to tell a scripter about this.)
When you did all this you tell a scripter how your triggers are named and ask to write a simple script that checks that both triggers are active by the end of the mission when a player lands and loads the next mission or the same one in case one of the triggers is not active.
Then maybe someone gives you a script for mission No.1 and you will need just to copy it and change filenames in it to be suitable for mission No.2, etc.
Then you can ask for more functionality like finish the mission if player is landed in a different place or is killed or time has run out, but you have to be very specific and go one step at a time from a simple script to a more functional.
You would not get help if you are not specific enough or you do not know what you want to do in details. You can start a new thread and copy this information to it if you agree with this approach.
