I remember a mine clearance presentation that described the petal mine. We were told that they were developed by the Russians for use in Afghanistan and made of brightly coloured plastic and were very light weight.
The design was for them to be thrown from helicopter doors over villages.
The kids would see them and play with them with the resulting limb and torso injuries.
We were horrified, more so when they were sown into cuddly toys with delay timers and tilt switches.
There was a quick realisation that the Russians didn't play by the same rule book as we did.
