When is it permissible to walk under loaded ordnance?

Walking under loaded ordnance is prohibited at all times due to the inherent risks involved. Loaded ordnance can include munitions that are potentially unstable and could discharge under certain conditions, leading to catastrophic consequences. Safety protocols are established to minimize the risk to personnel and ensure operational safety.

The rationale for the absolute prohibition is based on safety-first principles in military operations, where the potential for accidents or malfunctions exists. Even during operational activities that might suggest otherwise, such as during takeoff or emergency procedures, the risk remains too high. Safety pins and other securing methods might mitigate some risks but do not eliminate the danger associated with being near live ordnance.

Thus, the answer indicates that safety precedes operational efficiency, highlighting the commitment to protecting personnel in any situation involving explosives or munitions.
