The Avenger, also known as AN/TWQ-1, is an American self-propelled surface-to-air missile system. It is designed to provide mobile, short-range air defense protection for ground units against various threats including cruise missiles, unmanned aerial vehicles, low-flying fixed-wing aircraft, and helicopters. The Avenger’s mobility is one of its key strengths. It is designed to be deployed rapidly to any location on the battlefield, and it can operate effectively in a variety of terrain and weather conditions. The system is air-transportable, which means it can be transported by helicopter or C-130 transport plane. This makes it ideal for rapid deployment to forward operating bases and other remote locations.
