The Czech Hedgehog is an anti-tank fortification that was used widely during WW2. The name was given due to the spiky appearance of its design, and they were most often made entirely of steel. These Hedgehogs were extremely effective at stopping tanks, and when used correctly they could easily make a street impassable. When a tank tries to push one out of the way, the Hedgehog rolls underneath the tank, lifting its treads off the ground and therefore disabling it. This impressive design is able to withstand 60 000kgs, and generally stands about 1.1m high. The arms are equipped with square feet to prevent it from sinking into the ground, as well as notches for attaching barbed wire. The most famous use of the Hedgehog was in the Atlantic Wall during the D-Day Landings. They were not placed on the beaches by the Americans to provide cover for the troops as many people think, instead they were strategically placed there by the Germans to rip out the bottom of the Allied Landing Craft denying them access to the beach during medium and high tide. This meant the troops and tanks had to unload further out during low tide, making them exposed to longer machine gun fire.
