The SA-18 GROUSE (Igla 9K38) has a 2 kg. high-explosive warhead.
Range of the Igla is estimated at 5200m and a maxium altitude of 3500m. SA-18 employs an IR guidance system using proportional
convergence logic. The probability of kill against an unprotected fighter
is estimated at 30-48%, and the use of IRCM jammers only degrades this to
24-30%. The SA-18 also comes in a naval version the SA-N-10 GROUSE (Igla-M).
