First when you get up to the sniping area crouch down in the window and
there is some ammo and health in the corner if you need it. Get that and
then snipe the first wave of soldiers with normal guns then when your
"comrades" say that there are panzershrecks, concentrate all of your
fire there and don't worry about the regular soldiers because they cant
aim too good. shoot the panzershrecks until you see a guy running up the
road with a heavy machine gun. shoot him and then go to the left window
and continue what I just said and you'll b fine
