Machine gunner and rifleman in Normandy

FILE - With a searchlight beam piercing through the night, a machine gunner and a rifleman are on alert as the British Canadian offensive drive continues, in July 1944, south of Caen, in the Normandy region of France. The D-Day invasion that helped change the course of World War II was unprecedented in scale and audacity. Veterans and world dignitaries are commemorating the 79th anniversary of the operation.
