General information on the mission
The fourteenth mission of Metal Gear Solid V takes place in a relatively small area, where you still need to complete quite a few objectives. This mission can be completed in two different ways - by finding and rescuing the Viscount on your own (the most preferable method, if you want to rank S), or by following the interpreter while trying to remain hidden. Apart from completing the main objectives, you can also, e.g. rescue the POWs and fulton large containers with valuable resources.
Note - Regardless of the method that you adopt, try to restrain and fulton the Afrikaans interpreter (you can replay the mission especially for the purposes of this objective). Thanks to this, you will be able to interrogate enemies during missions in Africa.
PRIMARY (1/2): Identified the Viscount - You cannot skip this objective because, you identify the Viscount right before you rescue him (primary objective).
PRIMARY (2/2): Extracted the Viscount - You can find and rescue the Viscount (by fultoning him or by escorting him to the chopper) still before he is taken to one of the cottages in the village, which is the best method of completing the mission quickly. If you fail to find him at the beginning of the mission, you can still rescue him from the cottage, before he is interrogated by the interpreter, or after the conversation.
SECONDARY (1/5): Identified the Afrikaans interpreter - You can tell the interpreter by the green beret that he is wearing. You can either identify him right at the beginning of the mission (if you are going to follow him), when he is traveling around the map, or after he reaches the cottage, with the Viscount in.
SECONDARY (2/5): Pinpointed the locations of the 4 prisoners from an intel file - The document is on the desk in the central cottage of Kiziba Camp. You can collect it at any moment into the mission (even after a POW has died, or has been fultoned).
SECONDARY (3/5): Extracted 3 prisoners being held at Kiziba Camp) - the first POW appears on the map at the beginning of the mission, net to the interpreter (he is escorted to the camp, if you do not rescue him immediately), the second one is in the main camp, and the third one is in the roadside shelter. You need to rescue all three before they are shot (this happens short after the interpreter interrogates them).
SECONDARY (4/5): Extracted a materials container at Kiziba Camp) - In total, you need to fulton four big containers: two of them are near the cages in the camp and two other around the building, where the Viscount is being held. To do this, of course, you need the CARGO 2 upgrade.
SECONDARY (5/5): Listened to all 4 prisoners' interrogations - from the very beginning of the mission, you need to follow the interpreter and listen to the interrogations, from a safe distance. You must not be spotted in the meantime, nor raise the alarm, or the interpreter stops doing his beat.
Preferably, you should play this mission at night. It is especially recommended if you are going to follow the interpreter and eavesdrop on the interrogations, because you must not be spotted then.
It is a good idea to take D-Dog along, who is going to prove helpful at locating opponents, while sneaking (this eliminates the necessity of keeping your eye out, and frequent using of the binoculars). You can take D-Horse if you want to complete the mission as quickly as possible, i.e. reach the first staying place of the Viscount. As for the gear, it is a good idea to select a suppressed sniper rifle, thanks to which you can eliminate the more inconvenient opponents. However, this is not required for successful completion of the mission. At the same time, make sure that you have on an outfit that provides you with the best camo.
