In its basic infantry form, the system comprises a missile in a sealed tube which is clipped to a launch tube prior to use. When required, the missile tube is attached to the rear of the launch tube, the target sighted and the missile fired. The launch, or "kick", motor (booster) ejects the missile from the launch tube, at which point four wings indexed at 45 degrees just forward of the booster nozzles spring open forwards, four tail control surfaces flip open rearwards, and sustained propulsion is subsequently provided by the flight motor (sustainer) which fires through lateral nozzles amidships and propels the missile to the target. An optical sensor on the sight continuously monitors the position of a light source on the missile relative to the line-of-sight, and then corrects the trajectory of the missile by generating electrical signals that are passed down two wires to command the control surface actuators.
