What is a characteristic of ammunition in Group S?

Ammunition in Group S is specifically categorized as items that minimize hazardous effects from any accidental functioning. This characteristic highlights the emphasis on safety and risk management associated with these types of ammunition. Group S items are designed with features that reduce the likelihood of an unintended explosion or other dangerous consequences, thus enhancing overall safety for personnel handling the ammunition.

The focus on minimizing hazardous effects is critical in scenarios where ammunition may be subjected to accidental impact, fire, or other conditions that could trigger a dangerous situation. By prioritizing the reduction of potential hazards, Group S ammunition serves to protect both the individuals who handle it and the surrounding environment.

This careful consideration in design contrasts with other types of ammunition or explosives that may not have the same level of emphasis on risk mitigation, making the correct answer reflect the core purpose of the items classified within Group S.
