bearly there

You enter the back area of the forest area after coming up the internal tunnel that bypasses 2 sentrys. As you walk down behind the rocks to the right of the tunnel exit you will see 2 guards talking to each other. One with a pistol will move away from the one manning a 50 calibre machine gun, heading towards the rear of that position.Eliminate the guard on the 50 cal. The next one to eliminate is a guard up the tower behind the 50 calibre he is using a mauser rifle so sneak up the ladder. Follow the guard with the pistol at the rear, eliminate him and just a bit further on is the Snooper Rifle, a Thompson m/gun plus health. Your next move is to circle back to the internal tunnel exit and eliminate the 2 guards near the road tunnel before working your way to the front of the compound. Watch for the guard on the tower with the mauser rifle.
