Round-the-clock close air protection of armed forces subunits, military and civilian assets from attacks by tactical aircraft (fighters, assault aircraft, fighter-bombers), fire-support combat helicopters as well as neutralization of cruise missiles and unmanned aerial vehicles in head-on and tail-chase engagements against clutter background and in countermeasure environment when they are visually observed.
The Igla-S MANPADS is a new-generation system with a new performance capability for this weapon type – high kill probability of such small-size targets as cruise missiles and unmanned aerial vehicles.
