How did beach obstacles sometimes provide cover for U.S. soldiers at Omaha Beach?

During the Normandy Invasion on June 6, 1944, U.S. soldiers landing at Omaha Beach faced intense, deadly fire from German defensive positions. As troops struggled to advance across the exposed beach, they often found themselves trapped in a "killing zone" with little to no natural protection.12

In this desperate situation, the large steel beach obstacles—which the Germans had originally installed to impede landing craft and destroy vehicles—paradoxically became the only available cover for the American troops. Soldiers used these structures, such as steel frames and log posts, as makeshift shields to protect themselves from enemy fire while they pondered their next move or prepared for the difficult sprint toward the safety of the seawall at the base of the cliffs.12
