Make a trigger in the "Switch" in the trigger make it to "End#1" and in the Activation say: ForceEnd. now you can make this easier by making a small radius area so as soon as you get from point A to point B it will end the mission. Just set the activation to BluFor so as soon as blufor gets into the radius it will end.
Now to make AI's continue by walking the same paths like a "Patrol", just set your two or three way points and for the last way point set it to "Cycle". Basically that says "Cycle through Point A and B". He will patrolling that area until he dies etc.
Hope I helped
