👉 An arrival weapon, also known as an EVA (Emergency Vehicle Activation System) or EW (Engine Weapon), is a specialized weapon mounted on certain vehicles, primarily police cars and ambulances, designed to be deployed during emergencies. These weapons are typically non-lethal, such as rubber bullets, tasers, or pepper spray, intended to subdue suspects without causing fatal injury. The primary purpose of arrival weapons is to ensure the safety of law enforcement officers and civilians by providing a non-lethal means of apprehending individuals who pose an immediate threat but are not dangerous enough to warrant lethal force. The deployment of these weapons is governed by strict protocols to minimize harm and comply with legal standards.
