Silent, but Deadly

You head out through the rough, sandy terrain. Nightfall has fallen. Advantage...you. You must complete the mission before dawn. No excuses. the platoon is now far behind you. The perimeter is only two hundred feet away. You hide your backpack underneath some brush. The rifle is your only friend. As you get closer to the enemies base camp, movement by a sentry making his nightly rounds comes toward you. You put his smelly body in your cross-hairs and put your finger on the trigger.
