FIM-43 Redeye

The FIM-43 Redeye was a man-portable surface-to-air missile system.

Development
The FIM-43 Redeye was first designed in July 1959. It developed several versions of the missiles, known as Blocks I, II, and III, each with a variance of the warhead. By 1965-1966, General Dynamics developed the final configuration, and was eventually mass produced in 1968.

During the 1974 Peace Walker incident, Big Boss managed to procure design specs after neutralizing a Hind A unit at Catarata de la Muerte while attempting to locate the AI Lab in Central Heredia. The MSF then developed their own version.

Post-Peace Walker
In 1984, 50 redeye systems were delivered to the Mujahideen during the Soviet Invasion of Afghanistan, which they used to shoot down Su-25s, Mi-24 and Mi-8 choppers, as well as various other Soviet aircraft. By November 1985, it was largely replaced by the FIM-92 Stinger, and the Redeye's service was discontinued by 1995, by that time more than 85,000 rounds were created.

While not necessarily all it could be performance-wise, it does provide infantry with excellent anti-air capabilities and is now widely used in the U.S. and throughout the free world. The missiles use a passive infrared guidance system, making them the perfect weapon to counter airstrikes by attack choppers. If you're going to be facing enemy aircraft in a mission, you can't go wrong with the FIM-43.|FIM-43 Redeye weapons description from Metal Gear Solid: Peace Walker
