Tom Clancy's Ghost Recon Advanced Warfighter 2/Recon in Force

Take over the Entrance
You need to reach the entrance of the quarry to allow the Mule to be deployed.

Before the entrance, there are four enemies in groups of two. They will either be coming around one corner at a distance, or be patrolling the small group of buildings.

As you approach the entrance, you will need to watch for a sniper on the sniper tower. The other enemies are located on the ground and can be defeated easily by your team, although one may try hiding next to a building.

Wait for Allies
Allied forces will arrive via helicopter. A Mule will be dropped, allowing you to resupply and collect different weaponry.

Clear the quarry
Clear out all enemy guards and equipment in the area.

The southernmost position is located near a water tower. Within this camp, enemies will hide in buildings but leave once they are ready to fight.

In the main quarry, there are three guard stations of note. Two are in the corner next to the artillery, and the third is composed of two soldiers with RPGs. To complete the mission, you will need to destroy the artillery positions in the far corners, and the rpg soldiers in the middle.

Watch for a sniper hiding in one of the middle buildings. In addition, enemies may engage from the sides of the quarry and reinforce from an area you believed was cleared.

Once all four locations are cleared, the loyalist forces will take care of the rest of the area. Blackhawk 5 will arrive to take you to Juaréz.
