Unexploded ordnance (UXO)

UXO appears as intact or partially damaged munitions that failed to detonate as intended. These may include shells, rockets, or dropped ordnance and are often visually recognizable as military munitions.

UXO does not have an intended trigger but remains unstable. Detonation may occur due to movement, interaction, or secondary effects, making it unpredictable and hazardous. UXO is commonly encountered in areas subjected to indirect fire or air-delivered munitions and may remain a threat long after initial contact.
