The Valmara series of mines (Valmara, Valmara 59, and Valmara 69) are Italian produced anti-personnel (“APERS”) landmines. The are what are known as bounding mines, which is to say that when they are tripped, the main charge of the mine is projected upwards before exploding. The airburst of the mine is designed to allow the fragmentation to cover a wider distance and cause more casualties.

The mine is non-electric and is activated by a tilt rod assembly, which is designed either to be stepped on or to be moved by a tripwire. Once the assembly moves far enough, lockballs release and a spring loaded striker (much like the firing pin of a firearm) moves forward to hit a primer which causes the expelling charge of the mine to activate. The main charge of the mine is propelled upwards in a similar fashion to a mortar, moving until the anchor wire in the base of the mine pulls a secondary striker into the detonator of the main charge, detonating it for a 15 meter lethal radius.

The mine has been deployed in numerous ways, sometimes taking advantage of it’s ability to be hooked to a tripwire.

The Valmara 69 is found in Angola, Egypt, Iran, Iraq, Turkey, Kuwait, Mozambique, Sudan, and the Western Sahara.

The mines were made by the company Valsella Meccanotecnica SpA, which was founded in 1969, ceased making mines in 1994, and was completely dissolved in 2004.

      Yeah, sometimes weapon enthusiasts forget that they are fangirling over things meant to kill (in this case very often innocent) people. But i guess killing is just just not socially frowned upon, as long as its “the bad guys”…

        I can’t unproduce the mines. I can laugh at the comedy number.

        If it earns me enough social credit to laugh once and a while, I’ve removed landmines from a historical trouble area in the world, which is more actual material improvement than any amount of internet finger wagging.
