Unexploded ordnance (UXO) refers to military munitions, such as bombs, shells, or grenades, that did not detonate as intended during or after a conflict. These items can pose significant dangers to people and the environment, as they may remain active and explosive for many years. UXO can be found in various locations, including former battlefields, training areas, and even urban settings. Efforts to locate and safely dispose of UXO are crucial for ensuring public safety and preventing accidents, often involving specialized teams and equipment to handle these hazardous materials.
