In environments where national security is at stake, the choice of fencing material and design must be based on stringent government or defense standards. For instance, high-security mesh fences used in military contexts typically have anti-cut properties, making it extremely difficult for intruders to breach them with tools. Additional reinforcements like buried mesh skirts or pressure-sensitive cable systems can detect and deter tunnel intrusions. In conflict-prone regions, some military fences are designed to resist blasts or ballistic impacts, providing protection not only from trespassers but also from explosive threats.
