The Dragons teeth of the Siegfried line are not shown as they really were (and in numerous places still are today). 1) In the movie the line is built with four rows of teeth. In reality the line is built with five rows. 2) The teeth are in reality not made in one size as shown in the movie, but in 3 different sizes, where the first and last rows contain the biggest pillars, the middle three are middle sized, and woven in the last row you can find the smallest. 3) The rows are not placed exactly behind each other. If you would see them from above, you would see an angle in the middle. 4) The rows of pillars are also not built in one line. If you would look over a row from the side, you would see a zigzag of pillars. 5) The pillars in the movie are too close to each other. In reality, the area between two pillars is so big, you can park a car between them (as is done by the author of this comment on numerous occasions).
