AT4: Saab’s Disposable Anti-Tank Rocket

The AT4 is a single-shot, fire-and-forget 84mm anti-tank rocket launcher adopted by NATO forces as standard infantry anti-armour equipment. Light, simple and battle-proven, it requires minimal training to operate effectively. The AT4CS variant adds a counter-mass system that neutralises back-blast, enabling use inside buildings and enclosed vehicles — a critical capability in urban combat.
