The Russian-Ukrainian conflict, why some of the anti-tank dragon teeth have a role, some have no effect, the main reason is that the dragon teeth are not used correctly, if you just put a few rows of this triangular conebrae cement pier, the effect is almost equal to zero, and a lot of cement and steel bars are wasted, the enemy modified tank can easily push away these dragon teeth, the correct operation is to fix these dragon teeth on the ground, form a whole, arrange them behind the bushes, or connect the dragon teeth with wire ropes, but the best way is to fix them underground, a little deeper, but the cost will increase exponentially, it seems that the research on fortifications is also deeper, and the practicality of this also needs to be tested in actual combat。
