Sniper Elite 3 Walkthrough: Halfaya Pass Part 2
There are soldiers everywhere, stay low and never walk into the open without scouting first and tagging with your biniculars.
The next area should lead up either right or left. Go right and up the hill to find guards and a generator. Kill the guards or run past. Really nothing here but intel and weapon parts, so kill them or don't then head down the hill and ontot he next area.
If you do decide to kill everyone and anything that moves in super awesome bullet time be sure to mask your shots with the generator that is plinking and banging on the rooftop.
Be careful as you will have to leap over to the roof and a fall could kill you depending on game difficulty.
