The launcher is normally operated by a crew of two, a loader and a gunner. The launcher is loaded by attaching a rocket container to the rear of the launcher. When the container is attached, the electrical firing circuit is connected. The rocket container is 626 millimetres long and weighs approximately 3.2 kilograms. On the left side of the launcher is the 3× APX M 309 optical sight, which is graduated between 100 and 1,000 metres. The launcher has a shoulder rest and left hand forward grip, both of which may be adjusted to suit the firer. The right hand pistol grip contains a mechanical safety switch and the firing mechanism. When the safety is off, pulling the trigger generates a charge which fires the rocket.
