Video: Build 400m military fence in less than 1 minute

The US military has applied a fast, convenient RAID fence system that can build 400m of solid fences in just 60 seconds.

The fence can be easily folded, and erected with 90-degree squares.

The 2.13m high 400m-long military fence system is stowed in a small truck-sized container. Just fix one end of the fence to the ground, and when the truck moves, the fence also automatically extends and plugs in the path of the truck. The fence can be easily folded, and erected with 90-degree squares.
