Follow the road down from the observation point toward the lumber mill. As you near the bridge leading into the lumber mill, assume a crouched stance to activate your Optical Camo—enemy troops are posted on the other side of the bridge, including one behind a mounted machine gun. Take cover behind one of the lumber piles near the bridge. Before you deal with the enemy troops near the bridge, locate a rifleman standing atop a cylindrical tower attached to one of the lumber mill’s main structures. Peek over your cover and take aim at this hostile through your sniper rifle’s scope. As long as your weapon is suppressed, you can take this rifleman out without alerting the enemy troops near the bridge.
