Extract two prisoners from the village
You have already completed some objectives concerned with extraction of prisoners, therefore you should already be familiar with the general pattern. As for their locations, you can figure them out on your own (they have been marked in the above screenshot) or learn the locations by interrogating the enemy soldiers. In the latter case, you need to know Afrikaans, for the interrogation to be successful (you had the option to extract the interpreter in the previous mission).
After you have located a given prisoner, carry him out to the open and fulton him (you can also request pick-up and carry them over to the chopper at the end of the mission).
Find the rare plant near the village
The digitalis (lutea) plant is near the rocks to the East of Ditadi Abandoned Village. The exact location has been shown in the above screenshots. Also, you can use the help of your Intel Team to locate the plant, thanks to which the icon for the plant appears on your map.
Extract the truck
Unarguably, this is the easiest objective to complete. The truck is parked near the main crossroads in Ditadi Abandoned Village. You should fulton it at the end of the mission, because this may alarm the nearby guards. Of course, to fulton it, you require the CARGO 2 upgrade (for extraction of heavy equipment).
