Drachenzähne

Drachenzähne  or Dragons' Teeth formed part of several fortified lines in WW2 and later - most notably the Maginot and Siegfried lines and the East German border.  I understand that Switzerland still maintains several stretches of such obstacles, where they are entertainingly known as 'Toblerone lines.'  Perhaps there is scope for a game where the assault engineers have to eat their way through the defence lines?
