Which is NOT a common reason for engagement failure?

• A. Incorrect target type
• B. Range miscalculation
• C. Loss of lock
• D. Weather effects

Answer: (A)

Firing and guiding a Stinger relies on keeping a solid track on a suitable target and delivering a guidance command that matches the target’s conditions. The failures you’d expect to see most often come from factors that directly affect the seeker and guidance: range miscalculation throws off the fire-control solution and the missile’s intercept point; weather effects reduce infrared signal quality and can make tracking unreliable; loss of lock ends the guided flight, making a hit impossible. Selecting an incorrect target type isn’t a typical failure mode of the engagement itself. It’s more of a planning or targeting step issue, something that would be addressed before or during setup rather than during the actual engagement.
