Refinery - "Coiled Viper" (4)

Immediately save and open your command map. You start northwest of the refinery. The east bridge is south of the refinery, the south bridge is south of the east bridge, and the train station is the final objective. Head east into the path with Alpha. Run quickly, stopping to let your reticule steady when you see the enemy jeep. Eliminate the driver and the two enemies that emerge from behind it. Continue to the rock, turn right (southwest), and round the corner to shoot the enemy crouching uphill. Take out the two enemies lying down on the other side of the rock. Four more enemies will appear northeast; eliminate them. A jeep will approach from the east; take out the driver and passenger. Follow the hill and eliminate the enemy trailing the jeep. Equip your rocket launcher. You should be west and slightly south of the refinery's main entrance. Shoot a rocket at the enemy at the entrance, likely taking out another enemy behind him. Quickly switch to Guram Osadze and lay a sensor at the entrance. Switch back to Nigel Tunney and quickly circle the entrance to eliminate three enemies emerging. Switch back to Guram Osadze, head east until your indicator turns red, and place your last sensor to reveal two more enemies. Go as far east as possible and look south to find two more enemies. The final enemy is in the southeastern part of the refinery; eliminate them. Save the game, as the most challenging part is now over.

Switch to Bravo and regroup with Alpha inside the refinery. Open your command map and zoom in. Locate the white building in the southwestern corner of the refinery. Set a waypoint on the "X" mark for Alpha and hold 'A' to bring up the yellow light, pointing it south. This creates a path for Alpha to reach the house. Once they arrive, set them to 'Hold' and 'Suppress'. Take Bravo to the southeastern exit of the refinery and save once Alpha reaches their destination. While clearing the east bridge, Alpha will engage enemies to the west. Crouch by the left door and lie down as you reach the end of it. Peek around the corner to see the bridge. Five enemies are present: two to the left, two to the right, and one on the bridge. Eliminate all of them. Then, assist Alpha, who is engaging four enemies to the south around a rock. Kill these enemies. Switch to Klaus Henkel, go to the east bridge, walk onto it, and plant a demo charge. Return to Bravo, turn Alpha off 'Hold' and 'Suppress', switch to a Bravo team member, and save.

Open your command map. To the south of the refinery, you'll see a large rock with a small path to its right. Leave Alpha behind and follow this path until you can see the south bridge. Crouch and eliminate the four enemies at the bridge from left to right. Proceed slowly along the rock and eliminate one more enemy positioned between the previous group and the enemies Alpha was engaging earlier. Look west to find a fence with an opening and a winding path. Follow this path and eliminate the enemy on it. Switch back to Alpha and have them join Bravo via the path they took.
