Two civilian engineers are being held captive at Ngumba Industrial Zone, SW Guard Post and you need to rescue them both. In order to get there, though, you'll have to go through Munoko ya Nioka Station, which is filled with quite a few enemies. On your way, you'll get a report that some enemies are on their way to the guard post.
These enemies are coming in a vehicle and will be separating the prisoners by taking the female one to Munoko ya Nioka. A good idea, then, is to subdue and extract all of the enemies at Munoko prior to the prisoner's arrival, making it very simple to take down any other enemies that show up before rescuing the prisoner.
However, after the female prisoner is brought to Munoko, the male one at the original position will stumble away from his captors and likely get caught by a patrol vehicle. If this happens, then they will receive orders to kill him, which will result in you failing the mission and having to replay from a checkpoint. Thus, you have to make a choice about how fast you want to go in this mission.
One choice is to deal with all of the enemies at Munoko, preferably as quick as you can, then start going to the guard post where the prisoners are located. If the female prisoner is already on her way to Munoko, then don't worry about her, as they won't harm her. Your first priority is to get to the male prisoner before he is caught and subsequently killed. After that, return to the female prisoner and rescue her to finish the mission.
Mission Task 3
Nubians are goats and you can find a bunch of them hanging around Guardpost #20 on the map. It might be a good idea to go after these before anything else, as it's been known that they can exit the hot zone should they get spooked by you or the enemies.
Mission Task 4
You should be able to find one four-wheel vehicle sitting at Guardpost #20 on the map. If you wait long enough, however, another will come, so you simply need to wait for it to come in order to grab it.
Mission Task 5
You can find four materials containers at Guardpost #16 on the map. Note that if you've extracted them while freeroaming prior to this mission, then you will need to complete 5 main missions (replays count) before they will spawn again.
Mission Task 6
The African Peach you need to complete this task can be found on a cliffside right outside of the southeastern gate at Munoko ya Nioka Station.
Mission Task 7
You can find a Martial Eagle flying around near Munoko ya Nioka Station. Bring D-Dog along with you to help find its exact location, then either wait for it to land somewhere or shoot it with a tranq dart while it's flying. Extract it to finish the task.
