World War 1 sniper rifles

[Riter]

BTW, during the American Civil War, Union soldiers at Vicksburg used mirrors to aim their rifles at the Confederaates and this allowed them to shoot without exposing themselves to retaliatory fire. By the time they reached Georgia, they drilled holes in their stocks and stuck the wire handle of a hand mirror for the same purpose. This predates the periscope rifles of WW I.
