Tom Clancy's Ghost Recon Advanced Warfighter/Mayday! Mayday!

After an encounter with anti-air artillery, you are forced to deploy in a hostile fire area.

During this mission, you are given a drone to spot enemies for you. It should be used extensively in order to detect incoming enemies or to spot enemies in their patrol route.

Destroying anti-air
The first ADAT is located west of your position, and is guarded by only a few soldiers. When you destroy it with a C4 charge, four enemies will approach from the north.

The second ADAT is located within a scrambled area. Even though the region is supposed to be scrambled, the map marker gives the exact location of the AA defense. When you enter the scrambled zone, enemies and objectives will not be shown on the hud; however, you can still use the drone to visually spot enemies through its camera. When the second ADAT is destroyed, two cars will approach and park on the road north of the destroyed ADAT.

The final ADAT is located to the north in a small enemy camp. When it is destroyed, a vehicle in the camp will approach and deploy it's soldiers.

Once the ADATs are taken out, you will receive a new objective to destroy two artillery units in the castle area.

Artillery
There are two artillery pieces to be destroyed. The first is in an open area south of the castle, and the second is within the castle itself. To destroy them, you need a clear line of sight with the artillery and call the Apache to destroy the target.

From the third ADAT, head either north-east or south-east until the castle is in view. If you choose the south-east path but are getting overwhelmed by enemies, try a detour to the south-west first. In either case, there are two routes to the castle; the main access ramp is on the eastern edge, and there is a small foot-path located just west of the southern artillery.

The southern camp has a few guards on patrol. If you approach from the west, there is a soldier at the corner of the building that is facing away, as well as a soldier at the north-east tree; however, the view of the artillery is blocked by a truck, requiring you to enter the camp. If you approach from the east, there is a machinegun nest as well as a few soldiers within the tent area; however, the artillery is in plain view.

The second artillery is located within the castle itself. There is only one way in or out of the castle, via the ramp. To the right of the ramp, there are three soldiers patrolling the path. There is a small camp north of the castle, which has a machine gun nest and a few soldiers as well. The ramp leading to the castle has two solders, and the sole entrance to the camp is covered by a machine gun nest. There is also a sniper on the balcony in the castle. To destroy the second artillery, you need to enter the castle, since the direct line of sight is blocked by a truck.

Extraction
Once the artillery is destroyed, head to the north-east for extraction.

Bugs

 * From the third ADAT, if you try taking the north-east route to the castle, you will fall through the terrain. This occurs whether you move directly to the north-east or try an indirect route from the north-west. For information on fixing this, see.
