Which of the following is NOT considered hazardous material in munitions?

The answer identifying paper and cardboard packaging as not being considered hazardous material in munitions is correct because these materials are generally regarded as safe for handling and do not pose significant environmental or health risks when used in military applications. Unlike explosives, certain chemicals, and radioactive materials, which are regulated due to their potential dangers during storage, transport, and use, paper and cardboard are commonly used for protective and packaging purposes within the logistics of munitions without the same concerns. Thus, they do not fall under the category of hazardous materials as defined by safety regulations pertaining to munitions.
