Anti-tank obstacles

Anti-tank obstacles

Different antitank obstacles were constructed in fortified regions to impede the enemy’s armoured vehicles. In our Complex you may find Czech hedgehogs and dragon’s teeth (made of reinforced concrete, metal, and wood).

Czech hedgehogs are one-meter-high and are usually settled on solid ground. The distance between them was not more than two-thirds of a tank’s width, so when the enemy’s armoured vehicle was trying to avoid the obstacle it touched the nearby hedgehog anyway. Elaborated arrangement of Czech hedgehogs would stop a tank attack with a 90% probability.

The Czech hedgehog's name refers to its origin in Chechoslovakia, where they were first used. In USSR they were tested by Major General Gorikker. The tests proved high effectiveness of a “six-pointed star” (that is how he called the device). In wartime Czech hedgehogs were used in city battles and became a symbol of the Great Victory.

Dragon’s teeth are dug 1 meter deep into the ground at an angle close to 75 degrees and are arranged chessboard fashion. Such arrangement does not allow a tank to pass between the obstacles. During the war they were used for the protection of big cities like Moscow, Leningrad and etc. Mostly the dragon’s teeth from high-endurance fortification concrete were used, but they could also be made of granite and touchstone.

Dragon’s teeth were mostly used by the Germans and the Finns while constructing their defence systems.
