On 27 May, the Indian Air Force suffered its first fatality when it lost a MiG-21 and a MiG-27 in quick succession.[68][69] The following day, while on an offensive sortie, a Mi-17 was shot down by three Stinger missiles and lost its entire crew of four.[3] Following these losses the IAF immediately withdrew helicopters from offensive roles as a measure against the threat of Man-portable air-defence systems (MANPAD).
