Juno Beach on D-Day, 1944. The barbed wire fence is crude and not very high.

Note the soldier in the background, forced to use a ladder.

The deadly result of enfilade fire during the Dieppe Raid of 1942: dead Canadian soldiers lie where they fell. Trapped between the beach and fortified sea wall (covered with barbed wire), they made easy targets for MG 34 machineguns in a German bunker. The bunker firing slit is visible in the distance, just above the German soldier's head.
