Low visibility,inconspicuous obstacles installed on the ground. With a machine woven into a loop, when it opens, it covers theground, preventing people from entering the closed facility andstopping intruders who are walking or driving from moving.When a person tries to cross this area, they are confused, thereis no way out of the chaos, and there is no outside assistance.When an armored vehicle or tank passes by, the wire mesh spinsaround the wheel, turning into a metal plate in the chassis, makingit impossible to move and difficult to remove from the wheel.
