In the cemetery there is a hut. In the hut are some boxes. Jump on the low box next to the window, then jump towards
the window facing the wall. As you are about to hit the window, crouch and you can go out the window. You can shoot from that side of the hut. There is also a tractor there. You can jump up the front of the tractor then jump on to the roof of the hut. This is a very good sniping location, but you can be shot if spotted.
