Barbed wire fences and protective barbed wire

Barbed wire, mainly used to slow down the movement of infantry and vehicles, is divided into two types: fixed and mobile. The fixed barbed wire is constructed with barbed stakes and iron wires; the mobile barbed wire is produced in batches by the factory and then transported to the battlefield for temporary installation. The diameter is 70-90 cm and the length is about 10 meters. It has high destructive strength and can slow down the movement of vehicles such as automobiles and armored vehicles. When mentioning barbed wire, people usually think of special scenes such as battlefields, prisons, and borders. Indeed, once the barbed wire was invented, it was widely used in military and defense projects; now in the peaceful age, the barbed wire is also widely used.
