Metal Gear Solid V: The Phantom Pain Walkthrough – Mission 9: Backup, Back Down

You have 15 minutes to destroy as many vehicles as possible. You have two options: either destroy the vehicles using explosives or extract them with a +2 Fulton. The latter is the better choice, as it's more resource-efficient and provides you with tanks and APCs for later missions or combat team deployments. If necessary, manually assign soldiers to R&D or head out into the field to capture more. If you successfully destroy or Fulton all the vehicles, you’ll trigger a bonus segment where three tanks and a gunship will be sent to hunt you down. You need to eliminate these to complete the optional objective related to the tanks.

During this mission, vehicles will be moving from south to north, except for the jeep carrying the prisoner, which travels from north to south. It’s advisable to deploy north of the Yakho Oboo Supply Outpost, as shown above. You can set up an effective ambush point on the road and wait for the enemy to approach you (stealth option). Alternatively, you can choose to blow everything up (loud option). If you opt for a stealth approach, you can still take out the gunship that appears after the main portion of the mission by using the special weapon from the transport.

One recommended route is to establish an ambush point just south of the last outpost at the edge of the map, near your drop-off. Use the vehicle you deployed with as a blockade, ensuring it is positioned down the road rather than across it. If you park the vehicle across the road, the AI will not recognize it as an obstruction and will drive through without stopping.

When approaching the APC, make sure the turret is facing away from you to avoid being spotted while you Fulton it out. Alternatively, you can set up a roadblock using a decoy to distract the enemy.

Repeat the process for all the vehicles to complete the mission. Keep in mind that the last two may only reach the Yakho Oboo Supply Outpost in the final few minutes, so you’ll need to act quickly to extract them before time runs out. Alternatively, you can rush in to destroy them, as there is no requirement to extract any of the vehicles to achieve an S rank.
