What does "unexploded ordnance" (UXO) refer to?

"Unexploded ordnance" (UXO) specifically refers to munitions that have been fired or dropped but failed to detonate as intended. This can include bombs, shells, grenades, and other explosive devices that remain dangerous because they have not detonated following their intended use. The significance of UXO lies in its potential hazard, as these items can explode if disturbed or handled improperly, posing a risk to both military personnel and civilians.

In a broader context, understanding UXO is important for military operations, land management, and safety protocols in areas that may have been subjected to military activities. It highlights the need for careful handling and investigation of areas where munitions have been used, ensuring that appropriate measures are taken to manage the risks associated with these remnants of warfare.
