FIM-43 Redeye

The General Dynamics FIM-43 Redeye is a man-portable surface-to-air missile system that uses passive infrared homing to track its target. Production began in 1962 and ended in the early 1970s after about 85,000 rounds had been built, in anticipation of its successor, the FIM-92 Stinger, and the Redeye was gradually withdrawn between 1982 and 1995 as the Stinger was deployed, though it remained in service with various armed forces for some time after and was supplied abroad through the Foreign Military Sales program under an export ban meant to keep it from terrorist hands. Despite similarities to the Soviet 9K32 Strela-2, the two missiles were not identical, though the CIA concluded the Strela-2 had benefited from the Redeye's development.
