The Storm mounts the powerful long-range AT-6 Spiral anti-tank missile on the MT-LB armoured gun tractor. This combination makes for a low profile anti-tank vehicle that is hard to detect in well-concealed ambush positions. The Storm supplements the AT-5 Spandrel antitank vehicles used by anti-tank units. However, as a superior anti-tank weapon, Storm equipped units are intended to stop enemy armoured breakthroughs.
