When General Omar Bradley, Commander-in-Chief of American ground forces during the Normandy invasion, saw Cullin’s invention at work, he ordered them into full-scale production. Soldiers collected the iron anti-tank jacks the Nazis had scattered across Normandy’s beaches and transformed them into hedgerow cutters, which were bolted to virtually every tank in the First Army. General Bradley made certain the Rhino tanks were not used until the launch of Operation Cobra. Their effectiveness, further enhanced by the element of surprise, gave the American forces an important morale boost and helped them push deep into German territory. The Rhino tank was so helpful to the invasion that the 29-year old Sergeant Cullin was awarded the Legion of Merit for its creation.
