Answer 1

Some of the barriers are thrown together quickly with some steel that was nearby.

Purpose built Czech hedgehogs are a lot heavier and more robust. [https://en.wikipedia.org/wiki/Czech_hedgehog#/media/File:Rozsoch%C3%A1%C4%8D.jpg](https://en.wikipedia.org/wiki/Czech_hedgehog#/media/File:Rozsoch%C3%A1%C4%8D.jpg)

According to my father who was a professional soldier all his working life, for maximum effect these hedgehogs should be placed in 2-3 rows and tied together with steel cables. Then the steel cables should be anchored to the ground somewhere to prevent the enemy from pushing or pulling it away.

To prevent infantry from getting to close to the barrier and messing with it some anti personel mines or Claymore directional anti-personnel mines should be placed around it.
