When playing the Marine's side (wooden shacks and the field), in the back building with the turret there is a dumpster besides it, against a ground window. Crouch and sit inside the building behind the dumpster. You can snipe out of the window down the side alley. Also in the back building, go up the stairs and turn left. There is a table beside the stairs. Climb onto the table then onto the railing (banister). This may take a few attempts. Jump across the stairs onto the gray ledge with the fencing. From here you can snipe the entrance to the field and the big concrete building on your side.
When playing on the OpFor/Spetznas side (the destroyed concrete buildings), as soon as you start go straight to the hole in the ground. Directly in front of it should be two roadblocks. Go prone (lie down) and look between them. From here you can snipe across the street to the opposite concrete building (helicopters can see you).
When playing on the OpFor/Spetznas side, go down the street and up the stairs on the left. There is a sheet metal ledge that you can stand on. Stand on the edge of the sheet metal and look to the left (back to your spawn point). You can see an opening in the side of the building. Sprint jump off the end into the side of the building. This may require a few attempts.
