Destroy the Anti-Air Emplacements | Side Ops and Extra Ops MGS V: Ground Zeroes Guide
Last update: 11 May 2016
You start on the rocks in the southern part of the map. Your objective is to destroy three of the four AA guns marked on the map. If you want to complete the mission quietly, place C4 on those three or four guns and use the detonator after reaching a safe spot.
After the explosion, you will notice an armoured vehicle arriving from the west. You can take care of it using C4 or grenades.
In a warehouse to the right from the steel tower, you will find some mines, which you can plant near the entrance to the base. Place C4 there also and it will be enough to eliminate the armoured vehicle. One of the guards near the barracks is carrying an RPG. You can use it to destroy the targets. Destroying the AA guns and the vehicle are your only main objectives in this mission.
You can also rescue three of the prisoners, and one "special" prisoner, who is being held under the main base (in the place where you find Paz in the first mission). Rescuing this prisoner will be rewarded with obtaining the cassette Chico's Tape 7. To free the prisoner, you have to find him beneath the base and then carry him to the landing zone. For rescuing all of the prisoners (the ones in the cells by the shoreline and the one in the undergrounds) you will get the "Extraction" achievement.
You can use the truck parked in the courtyard as well. It can be easily reached by going an unconventional way: Leave the lower base and turn right after walking through the red door. Crouching, make your way to the other side of the courtyard. Stick to the right side of the wall.
If you plan to rescue the three prisoners, you have to do it before destroying the AA guns. You can place C4 first, but do not detonate the explosives. After extracting the prisoners, you can complete the remaining two objectives of the mission and after that, you have 3 minutes to escape the base.
Alternative way - fast and noisy
You can complete the mission very fast by using an AA gun. First, you have to destroy the gun that is located to the west from the base. Then, use the one that is closest to the starting point to destroy the rest of them. If you wait for a while, you can destroy the armoured vehicle with it as well. Afterwards, you can only escape the base.
