Other UXO

During the war in addition to bombs, cluster munitions and mines the conflict ‘required’ a multitude of other weaponry, not all of which functioned or was used as originally intended. Within technical reports detailed nomenclatures and types are recorded, but only in general terms, and hence within Lao, these are referred to as a blanket fashion as ‘other UXO’.

What are they?

Land service ammunition from ground battles, hand grenades and rifle grenades, mortars, artillery projectiles, anti tank rockets, and rifle munitions, to name some of the most commonly found.
They also include air to ground rockets like the US 2.75 inch or the ground to air types going as large as the Soviet SA2 surface to air missiles.

Other UXO can contain high explosives, flares or illuminating compositions, smoke producing chemicals like White Phosphorous or lachrymatories like CS.

Around 50% of the recovered UXO annually fit into to the ‘other UXO’ category. Some of them are UXO that have been fired and failed to function, others may have been left abandoned near old military sites, whilst others were ‘kicked’ out as a result of an explosion maybe as they were being transported. The risk from ‘other UXO’ varies, some of the rifle grenades for example can be extremely hazardous to touch and move, whilst other items are reasonably safe to handle and may not even be fuzed. BUT like UXO in general it is not always possible to know the condition of an item by simply looking at it.  

Common examples include: 37 and 57 mm anti aircraft projectiles, 81 and 82mm mortars, 105mm artillery projectiles, 2.75 inch rockets, M23 white phosphorus igniters used in association with napalm or fire bombs etc. Unlike the bombs and cluster bombs, which originate from the US, the category of other UXO covers a more balanced range of munitions from all sides of the conflict
