This is a repeat of an earlier mission called Occupation Forces, only this time you must complete the mission without any help from Supply Drops, Buddy Support, or Fire Support. Additionally, your weapons and items are unavailable, so you must subsist on the equipment you find at the enemy location. However, you still have your Fulton Recovery Device at your disposal, which we will take advantage of in this mission.
Start by selecting the landing zone in the west, to the left of the Sakhra Ee Village. This will put you in a good position to intercept the convoy en route to their destination. You will be heading to a section of the road located about halfway between the two outposts in the northwest. Feel free to put a custom waypoint on your map if you wish, and begin heading to that location.
On the way, you will pass by the outpost indicated by the ‘07’ on your map. Curve around to the right to completely avoid this outpost. Continue to head northwest along the road. You know you are in the right area once you reach a small empty house on the right side of the road.
You’ll now see the convoy heading toward you on the road. All you have to do is simply hide along the roadside, staying prone until they get really close to your position. Then, jump out to reveal yourself, causing the vehicles to stop.
With the convoy stopped, quickly run up to the side of each vehicle and extract them with your Fulton Recovery Device. It turns out the colonel is in one of these vehicles too, so extracting him while he’s inside completes a mandatory objective.
After you have extracted all the vehicles in the convoy, simply head to the helicopter landing zone and board your helicopter to conclude the mission. Your speedy completion time alone should be enough to secure the S Rank.
