General information on the mission
The fifteenth mission of Metal Gear Solid V is one of the shorter, and less complex, ones. Your character needs to explore the village, where there are four Walker Gears and either destroy or fulton them. It is recommended that you operate in shadow here, because the alarmed soldiers start using the Walkers, which makes the mission more difficult. There are three secondary objectives here - rescuing two POWs, locating a rare plant and fultoning the military truck.
PRIMARY (1/1): Eliminated the Walker Gears - Although this is possible, you do not need to destroy the Walkers (for this, it is best to use a good rocket launcher). It is a much better idea to extract them, thanks to which you complete the second secondary objective.
SECONDARY (1/4): Extracted 2 prisoner being held at Ditadi Abandoned Village - You can either find the POWs on your own, or find out about their locations by interrogating enemies. It is best to fulton them back to the Mother Base.
SECONDARY (2/4): Extracted all Walker Gears - This objective is connected with the primary objective. After you find the four Walkers, you need to fulton them and it is best to do this after you have eliminated nearby enemy soldiers. You can fulton the Walkers only if you have the CARGO 2 upgrade.
SECONDARY (3/4): Picked a digitalis (lutea) at Ditadi Abandoned Village - You find the plant in the upper part of the village, close to the rocks that you can climb. You can use the help of your Intel Team, thanks to which it will be marked on the map.
SECONDARY (4/4): Extracted a truck at Ditadi Abandoned Village) - The military truck is parked near the main crossroads in the village. To fulton it, you need to have the CARGO 2 upgrade.
It is best to take on the mission after dark, thanks to which it is going to be much easier to near the Walkers and steal them. As your buddy, you should take along the D-Dog, who sniffs out all of the enemies and is going to make it easier to either avoid or eliminate them.
What gear you take along does not really matter, if you want to fulton all of the Walker Gears. If you cannot do this (because you do not have the CARGO 2 upgrade) take a good rocket launcher and/or explosives along.
