How to create these kinds of objectives?

[NTULINUX 1]

Hello everyone!

I have a mission I am working on which involves infiltrating an area and neutralizing all hostiles within a certain a/b axis trigger, then I want the team to regroup at the FOB after the objective has been finished, ultimately ending the mission.

1.) How do I create a mandatory objective within a mission and have it show up as a task, i.e. "Neutralize all enemies within the target zone." I also want all players to know the area of which they are supposed to secure, such as a waypoint that automatically shows up on their screen or just simply a marker on all the players' map.

2.) After that objective is complete, how do I then create another objective which ONLY ACTIVATES once the first objective has been successfully completed. For example, the current task switches to "return to FOB."

I do not want players cheating and going straight to the FOB, I want the area to be cleared out first.

I have a basic understanding of how to create objectives / tasks, but to specifically clear out a wide area with absolutely no hostiles within the given radius, then ordering the human players (and their squads which may or may not have AI) to move to a certain location, I have no idea.

Thank you!
