Two categories of targets can the Stinger engage?

• A. Helicopter and fixed-wing
• B. Air and ground
• C. Jet and non jet
• D. Jet and helicopter

Answer: (C)

The Stinger uses an infrared seeker to home in on heat sources, so targets are effectively grouped by propulsion type: jet-powered aircraft and non-jet aircraft. Jets produce a strong, concentrated heat signature from their exhaust, while non-jet aircraft—such as propeller-driven planes and helicopters—also emit heat that the seeker can track. These two broad categories cover the airborne threats the system is designed to counter, making jet and non-jet the best way to describe the target classes.

Other options don’t fit as cleanly. The air-versus-ground distinction isn’t applicable because the Stinger is designed for air targets only. A helicopter and fixed-wing split omits many non-jet, propeller aircraft, and a jet-and-helicopter split leaves out propeller-driven, non-jet aircraft.
