What is required for ammunition and residue returns under the amnesty program?

The requirement for ammunition and residue returns under the amnesty program primarily focuses on using safe return methods. This emphasizes the importance of handling hazardous materials like ammunition and residues in a manner that prioritizes safety and minimizes risks during the return process.

Safe return methods likely include practices that ensure the materials are securely transported, properly contained, and that any potential hazards are mitigated. This aligns with the objectives of an amnesty program, which aims to facilitate the safe and responsible return of potentially dangerous items, thereby protecting personnel and the environment.

While the other options may seem relevant in various contexts, they do not directly address the specific requirements for returning ammunition and residue efficiently and safely within the framework of the amnesty program. Therefore, focusing on safe return methods is essential to ensure compliance and safety standards are met.
