👉 The fax weapon, also known as a stun grenade or stun fax, is a device that emits high-voltage electrical pulses to incapacitate individuals, typically by causing temporary paralysis or disorientation. It works by sending short bursts of electricity through a fax machine's internal components, targeting the heart or nervous system. While not lethal, these weapons are designed to disrupt communication and force victims to surrender or flee, often used in hostage situations or as a tool of psychological terror. However, their use is illegal and highly dangerous due to the risk of severe injury or death.
