In which two positions can 120mm white phosphorus rounds be stored?

The storage of 120mm white phosphorus rounds must adhere to specific safety and operational guidelines to ensure both accessibility for their use and safety during handling. Storing these rounds in a vertical position with the fuse end up is significant because it minimizes any potential risk of accidental ignition. The configuration also allows for better weight distribution and stability of the rounds while stored.

Horizontal storage is another permitted option as it is a conventional method that can effectively prevent damage or deformation to the rounds. Storing munitions horizontally makes them easier to transport and access, reducing the risk of impact or mishandling when retrieving them.

This combination—vertical with the fuse end up or horizontal—provides effective methods for safe and practical storage, ensuring that the rounds remain intact and ready for use when necessary.
