|Resistance member, Baron Lumber Mill||100 RP, $900|
Prepare for Ambush
Return to the Baron Lumber Mill once you’ve liberated it to find a Resistance member with another task for you. It seems more Cultist trucks are on their way to pick up more "Recruits", stage an ambush instead to put a stop to their abductions.
You’ll have 25 seconds to prepare for the ambush, make sure you’re stocked up on ammo and have an RPG-7 on you. Finally, head over to the gates and lay down some Proximity Explosives to surprise your visitors. Once your plans are set, get to a vantage point with your RPG-7 ready.
Destroy Prisoner Trucks 
Once the trucks arrive, hopefully your Proximity Explosives will do the majority of the damage. If the trucks are still about, use the RPG-7 to finish them off. The two pickup trucks should be ignored while you focus on the larger Prisoner Trucks, a rocket from the RPG is enough to take them out. With enough preparation you should find yourself not even suffering any damage as you conclude the mission.
