The Czech hedgehog is a static anti-tank obstacle defense made of metal angle beams or I-beams (that is, lengths with an L- or I-shaped cross section). The hedgehog is very effective in keeping light to medium tanks and vehicles from penetrating a line of defense; it maintains its function even when tipped over by a nearby explosion. Although Czech hedgehogs may provide some scant cover for attacking infantry, infantry forces are generally much less effective against fortified defensive positions than mechanized units.

The Gecko Normandy Beach Hedgehog in 1/35 scale from the plastic figure models range accurately recreates the real life invasion obstacles.
