Colonel Hobart (England) invented many vehicles that were used on D-Day. He invented amphibious tanks that could operate in water before landing on the beach ("Donald Duck", duplex drive tanks), he invented tanks that could fire flamethrowers, he invented tanks that could fire heavy mortars that could blast bunkers at point blank range, he invented tanks that could put down planks of wood that could give traction and support to tanks that ran on beach sandy ground so they would not sink in the sand. He invented tanks that could put down items so the tanks could get off the beach and get onto high ground. These tanks were called "Hobart's Funnies".
After D-Day, June 6, 1944, the Americans took German beach obstacles and fitted them to American M-4 Sherman tanks, called "Rhinos", and these pieces of metal ripped up the Bouchage hedge rows and enabled the Americans and others to break out of the Normandy Peninsula.
