[quote:3a5dd]How They Work

The missiles weigh about 30 pounds and are about 5 feet long. They can fit inside a large duffel bag and can be fired from the gunner's shoulder.

When operating the missile, the gunner aims at a target, starts the missile's power supply and pulls a trigger to activate the missile's target lock system.

The total time required to fire the missile is six seconds.

To strike its target, the SA-7 uses a heat-detection system to pursue a plane.

The missile self-destructs after 14 to 17 seconds of flight if it misses its target.
