Czech language test

The Czech hedgehog is a static anti-tank obstacle defense made of metal angle beams or I-beams.
It is similar in shape to a much larger version of metal knucklebones or caltrops.
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 Polabian language, also known as Drevanian–Polabian language, Drevanian language, and Lüneburg Wendish language, is a West Slavic language that was spoken by the Polabian Slavs in present-day northeastern Germany around the Elbe.
It was spoken approximately until the rise to power of Prussia in the mid-18th century – when it was superseded by Low German – in the areas of Pomoré, central (Mittelmark) part of Branibor (Brandenburg) and eastern Saxony-Anhalt, as well as in eastern parts of Wendland and Dravänia (Schleswig-Holstein), Ostholstein and Lauenburg).
Polabian was also relatively long spoken in and around the cities of Bukovéc (Lübeck), Starigard (Oldenburg) and Trava (Hamburg).
The very poorly attested Slavic dialects of Rügen seemed to have had more in common with Polabian than with Pomeranian varieties.
In the south, it bordered on the Sorbian language area in Lusatia.
