The AT4 is a shoulder-launched, anti-tank missile. This single-shot, disposable weapon is also known as the AT4-CS, with the “CS” designation meaning “confined space”. Built by Saab Bofors Dynamics, the AT4 has an 84mm warhead and a launcher casing made from fiberglass-reinforced material. The AT4 is designed to be recoilless and can be fired from enclosed spaces without the lethal backsplash. It was used during the US invasion of Panama, the Afghanistan War, the War in Iraq, and the French intervention in Mali.
