Sam Fisher- Windy Sniping

He braced the SC-20 against it and peered through the scope. Since he now knew where to look and what to look for, each sniper stood out clearly in the green of the NV. Fisher wasn't worried about the distance, but the wind over the plateau was moving at a good clip.

  He zoomed in until the scope's crosshairs were centered on the back of first man's head, then adjusted his aim eighteen inches to the right. He fired. In a blossom of dark mist, the bullet struck the man behind the right ear. Fisher zoomed out, refocused on the next man, zoomed back in and adjusted for windage, then fired.
