Too large to be manportable, it was typically deployed from specialised vehicles or helicopters. The missile was intended to supplement traditional anti-tank weapons like the 100 mm anti-tank gun whose accuracy beyond 1500 m is poor. The missiles' accuracy in contrast remained high as far as its maximum range of 2000 m. However the system's bulk, slow speed and poor combat accuracy drove development of later SACLOS systems like the AT-5 Spandrel.
