What should be done if the firing stud of the RPG-7 is not struck during a misfire?

In the scenario of a misfire with the RPG-7, if the firing stud has not been struck, inspecting the firing pin for damage is a critical first step. This action helps determine the cause of the misfire. A damaged firing pin could be a potential reason why it failed to strike the firing stud, preventing ignition of the projectile. Understanding the status of the firing pin can inform subsequent safety measures or necessary repairs, ensuring that any further attempts to fire are done with a reliable and functional component.

The other options may not align with best practices for safety and operational protocol. Waiting another ten minutes without investigating could lead to unnecessary risks, especially if there's an issue with the weapon. Removing the warhead directly without inspection could be hazardous, as it might still be armed or could be unstable. Similarly, firing again after merely checking could result in further malfunction or even an injury, particularly if the underlying issue with the firing mechanism is not properly diagnosed. Therefore, assessing the firing pin is the most prudent and safe initial response in the situation given.
