What is the primary role of the FIM-92 Stinger system?

• A. A man-portable air defense system designed to defend forces against low-flying aircraft and helicopters using a shoulder-fired infrared-guided missile.
• B. A surface-to-air missile used from fixed emplacements with radar guidance.
• C. A long-range intercontinental ballistic missile.
• D. An anti-ship cruise missile.

Answer: (A)

The essential idea is that this system provides short-range, mobile air defense for ground troops. It is a man-portable, shoulder-fired weapon that uses infrared guidance to track and engage low-flying aircraft and helicopters. Because it’s light and operable by a single user, it can be quickly deployed by infantry to defend units, convoys, or positions from threats that fly at low altitude. It isn’t a fixed radar-guided system, it isn’t long-range, and it isn’t an anti-ship or ICBM weapon, which is why the shoulder-fired, infrared-guided aspect best fits the Stinger’s primary role.
