Dragons Teeth (or Drachenzähne in German) are a form of static defence that was first deployed in WWII. Their purpose is to restrict the movement of tanks and sometimes (as in the Seigfried Line) funnel those vehicles into preprepared killing zones. Along the Atlantic Wall, they were often used in conjunction with landmines, anti-tank walls and ditches. Although they look like they are individual concrete blocks they were often laid as part of buried concrete 'mats' so they couldn't just be bulldozed out of the way. There were also some 'mobile' versions that could be moved and this sort of obstacle wasn't exclusively pyramidal in shape, although these are the most common. This type was typically 3-4ft tall, enough to ground any tracked vehicle that tried to cross them.
|These blocks were used around a Kent railway junction. The Pole in the top was used to hold barbed wide. These examples were relocated to Fort Amherst in Chatham.|
|These Bouy type blocks were designed to be used on roads and would have been chained together in pairs making them very hard to move. |
This set comes with ten individual teeth and I deliberately kept the bases 'muddy' so they would blend in if I used them with my existing country roads or in the fields either side. Having now taken some pictures I think I'll add some grass to half of them so I can mix and match depending on what terrain I use them.
