I made this barricade for my T-34/85 scene. It is very simple model 226 polygons. Max files is set for Vray render (you will only need to add hdri image)

The Czech hedgehog was widely used during World War II by the Soviet Union in anti-tank defense. They were produced from any sturdy piece of metal and sometimes even wood, including railroad ties. Czech hedgehogs were especially effective in urban combat, where a single hedgehog could block an entire street. Czech hedgehogs thus became a symbol of defense at all cost in the Soviet Union; hence, the memorial to Moscow defenders, built alongside the M-10 highway in 1966, is composed of three giant Czech hedgehogs.

Czech hedgehogs were part of the German defenses of the Atlantic Wall. During the invasion of Normandy, the Allies cut up sizable numbers of intact and wrecked hedgehogs, and welded them to the front of their M4 Sherman and M5 Stuart tanks. Known as Rhino tanks, these proved very useful for clearing the hedgerows that made up the bocages across Normandy.

Postwar tests conducted by Czechoslovak army proved the low efficiency of the metal hedgehogs against heavy armored vehicles such as the Soviet ISU-152 and T-54 or German PzKpfw V Panther. As many as forty percent of attempts for breakthrough were successful, for which the army developed new anti-tank obstacles for the purpose of the border fortifications activated during the Cold War. Nevertheless, the metal hedgehog was still used as the quick road-block against wheeled vehicles.(Source: WEikipedia)
