The launcher is normally towed by a ¾ ton 4 × 4 vehicle. It can also be airlifted by helicopter. The maximum rate of fire is 2 rds/s. The elevation is -1 to +50° and the traverse is ±12°. A 50 m cable is attached to the launcher for firing purposes. The maximum height of the rocket's trajectory is 4,000 m. The crew consists of four and reloads are carried in 16-round glass fibre containers. A battery will normally have four launchers each having at least 64 rockets available on its towing vehicle.
