Why were Robert edlin and other army rangers dropped off 75 yards from the shore?

Robert Edlin and other Army Rangers were dropped off 75 yards from the shore during the D-Day invasion of Normandy to avoid heavily fortified German defenses on the beach. This tactical decision aimed to reduce casualties as they approached the beachhead, allowing them to land in a less exposed area. However, the drop distance also presented challenges, as the Rangers had to swim to shore under fire, facing enemy obstacles and strong currents. Despite these difficulties, their mission was crucial in securing the beach and facilitating the larger Allied invasion.
