Tank net is a special defensive structure mainly composed of high-strength, corrosion-resistant iron wire, which can physically prevent or delay the movement and attack of tanks, effectively slowing down the pushing speed of tanks, and even stopping them completely, providing valuable counterattack time for the defenders. Anti tank wire mesh is mainly divided into two forms: first, it is 10 meters long, 4 meters wide, and 40 centimeters high, suitable for laying on the ground or in grass; second, it is composed of 10-20 circles stacked in a cylindrical
shape, with stronger stability and protection ability.
